These unusual lilacs are the offspring of blue and chocolate DNA. A chocolate/liver dog develops the same dilution gene that, as previously indicated, turns a black dog blue.
If a dog is brindle it is determined at the K Locus(location). Two sets of Genes can be held here at this location, ‘Ky and “Kbr. The “Kbr gene, also known as the brindle gene, is dominant over the “ky gene. If a dog carries one copy of brindle it is showed as (kbr/ky) in the K-Locus or two copies(kbr/kbr). If the dog have 1 or 2 copies of the brindle gene the dog will express a brindle coat. The “Ky gene, its known as the allowing gene. This is because when 2 copies are present it allows the A-Locus, the D-locus and B-locus to determine the dogs coat over all pattern. The “Kbr brindle gene interferes with the color expression of the A,D and B-locus giving you the brindle look
The daughter of our Aikido and Scarlet, here is our Marlee. Since Marlee and the entire litter she was born in were all brindles that carried fawn (Kbr/Ky), since Scarlet is a fawn (ky/ky) and Aikido possesses two brindle genes (kbr/kbr). Since the brindle gene is dominant, all puppies have the brindle appearance. Each of Marlee’s puppies will have a 50% chance of being brindle when she is bred, and 50% of her litter could be fawn if she is bred to a fawn dog (ky/ky).
Boy is this Locus crowded! The four genes held at this location are “Ay for Fawn, “At the tan and point or Tri-color gene, “a the solid black gene and “aw for sable. “Ay and “Aw are very similar and are dominant over, “At and “a, making it so the tan and point or Tri-color gene “At and the black gene “a are not noticeable in the dog. “At is dominant over “a, so if a dog is (At/a) at this Locus the dog will show the same markings as a dog that’s (At/At). If a dog is (Ay/At)(Aw/At)(Aw/a) or (Ay/a) the dog will be fawn or sable not showing the traits from the tan and point gene of the solid black gene. A Dog will only be full solid black if its carries two copies of the “a gene (a/a). A dog who’s brindle (kbr/kbr)( kbr/ky) will be brindle expressing itself over the A location. If a dog is (At/At) or (At/a) the brindling will be expressed where the tan points should be. If a dog is (Ay/At)(Aw/At)(Ay/a) or ( Aw/a) and carries 1 or 2 brindle genes the brindle will be expressed all over the dog. If a dog is (a/a) and carries 1 or 2 brindle gene the brindle is not expressed because since (a/a) is solid black and brindle is black that allows some fawn to come though there is no fawn to let though so the brindle is not noticed. If the dog is Ky/Ky not carrying a brindle gene it allows all genes in the A location to be expressed with our any interference.
At the A-Locus, our Napoleon is (At/a). “At” is the gene for three colors, whereas “A” is the gene for one color. The expression of the fawn’s tan tips is permitted since “At” is dominant over “a. His tan points would remain the same regardless of where he was, even (At/At) the A-Locus.
Here is yet another superb illustration. Here are two pups from Ocarina’s earlier brood. A Lilac Fawn with an A-locus of (Ay/At) is shown on the left. This is because “ay fawn is dominant over “At no solid color is allowed to be represented. The Lilac and Tan female on the right has an A-Locus that is (At/At), making her Tan points completely visible.
In my opinion, the French Bulldog breed’s solid (a/a) without brindle (ky/ky) canines have the most attractive coats available. This dog, named Velvet, is a solid shade of blue (d/d)(a/a). Because Velvet’s mother is (a/a) at the A locus (dominant black), she could only pass a (a) gene to her puppy (solid black). Since Napoleon is (AT/a), he inadvertently transferred Velvet’s (a) gene, causing her to be (a/a). She would have been (At/a) and not solid blue if Napoleon had given her his (AT) gene.
We have a Blue Sable Ocarina (coc0Bbawat). Sables have many coat types, some of which are more noticeable than others. She has a blue coat on her that competes with the fawn to give her an oaky color since the sable prevents the “At solid” component of her coat from fully expressing itself.
The blue Locus seems to be everyone’s favorite. A fun fact about the D-Locus is actually just a dilute gene. It dilutes(waters down) the colors that the dogs are in the K-Locus and A-locus. If a dog is solid black with 2 blue dilutes its becomes a solid blue dog! If the dog is a Fawn dog with 2 blue dilutes it becomes a Blue Fawn, champagne color.
This female puppy is Blue Fawn, one of our earlier litters (dd ayay). She is blue because she is carrying two blue dilutes at the D-Locus. She is at the A-Locus (ayay). She is (kyky) permitting the D-Locus to overpower the A-Locus at the K-Locus, where the A-Locus is free to express itself.
Our Azula is (dd At/At Kbrky), who is currently retired. She is accompanied by one copy of “She has tan spots that you should be able to see because she is (atat) at the A-Locus, but they are hidden by the brindling gene, kbr. You can see a slight brindling if you look attentively at her checks and paws since the “Tan points are being covered with kbr. Because the solid portion of the “At gene” is dominant over the “Kbr gene, you cannot notice any brindling on the majority of her coat. A dog carrying brindle would have no brindling on their coat if it were (aa) at the A-Locus.
This Locus work similarly as the D-locus. The CO-locus needs 2 copies at the Cocoa gene in each of its Allele for the Cocoa color to be expressed. Cocoa is a testable gene just like all the others.
These puppies are all from our Harmony and Max (cocoDdata kbrky) litter (DdCocoata kyky). These puppies include two who are (cocoDdata kbrky) and one who is (cocoDdaa kyky).
This Locus work similarly as the D-locus and CO-locus. The B-locus needs 2 copies at the testable chocolate gene in each of its Alleles for the testable color to be expressed. A French bulldog that is blue (d/d) and testable chocolate (b/b) is called and Isabella French Bulldog. A dog that is blue (d/d), Cocoa (co/co) and Testable Chocolate (b/b) is also called an Isabella French Bulldog. A dog that is Blue (d/d), Cocoa (b/b) and only carriers one or no copies of Testable chocolate is called a Lilac French Bulldog.
On the left is a solid shade of lilac that is created by combining two copies of cocoa and blue (co/co d/d a/a kyky). A solid Isabella with two copies of Testable chocolate and Blue combined is shown on the right (b/b d/d aya kbrky).
An Isabella and Tan with two copies of testable chocolate is on the left (bb dd atat kyky). A Lilac and Tan with two copies of Cocoa is on the right (coco dd atat kyky).
A chocolate and tan produced from two copies of Cocoa is on the left ( bb Dd ata kyky). Two copies of Testable Chocolate were used to create the chocolate and tan on the right (coco Dd atat kyky).
An Isabella fawn is on the left (bb dd aya kyky). Lilac fawn is on the right (coco bb aya kyky).
This Locus is called the Reverse yellow Locus but we know it as Cream : ) Cream is the most dominant gene is the Frenchie color pool if 2 copies are present in the Locus “e/e. If a dog carries two copies of cream at the E-locus (e/e) the dog will be completely covered in cream no matter what color or pattern the dog carries. In most cases if a dog carries one copy of the cream gene (E/e) a slightly lighter coat can be noticed on whatever dominant color the dogs coat is. So, for example is a dog is Blue(d/d) and carries one copy of cream so its (d/d E/e) the dog will appear at times a little lighter blue compared to a dog that carries no cream. If a dog carries 2 copies of cream on a blue dog so it’s (d/d)(e/e), the dog will be completely covered in cream.
The dog in question is cream and only carries cream; it also has two brindles ((e/e) (Kbr/kbr)). Since cream is the predominate color in a dog, no brindle is seen.
This is Naz, our infant son. He is a Blue Sable and carries one copy of Pied, cream, chocolate, and AT. ddBbayat Ee N/S You can see that he is not all white because he only has one copy of cream with him.
These are my personal favorite. There are many Tri color variations; Black and Tan, Chocolate and Tan, Blue and Tan, Lilac and Tan and Merle and Tans. What gives these dogs tan point markings is the Allele combination at the A-Locus. The “At gene is the main component in giving the dog its tri-color appearance. As mentioned before the At gene is dominant over the “a gene. So if a dog is (At/At) or (At/a) at the A-locus the dog will express its Tan Points. Apart from the dogs tan points what gives your dog its coat color is what Alleles your dogs carry at the D-Locus, B-Locus and M-Locus. The coat of a tri color dog that doesn’t carry 2 alleles of blue or chocolate base color is solid black.
This dog is a chocolate and tan color and has a clear point from Harmonies first litter. Hes (cocoDdatat kyky)
Napoleon is a chocolate and cream-carrying Blue and Tan dog with a distinct point. (ee ddCOcoata)
Our Max is a black and tan Merle who also has blue and chocolate in his coat. (Kyky Mm, DdCOcoata)
Lilac French Bulldogs
When each locus has two copies of each allele (d/d)(b/b), the resultant hue is a combination of the blue from the D-locus and the chocolate from the B-locus. If the dog has one or two copies of the “KBRgene,” the coat will typically be purplish or solid purple, depending on whether the dog is also solid black or tricolored. (a/a)(at/a)(at/at). The dog will be a lilac Fawn with a more yellowish champagne look toward it as opposed to a blue fawn, which would look snowier champagne, if it isn’t Tri color, solid black (a/a), or carries the brindle gene.
I’m Wolfie, the father of the ocarina. Around 2012, he was the first Lilac French Bulldog to arrive in America. A Lilac Fawn, he (ddbbayay kyky).
She is a Lilac Trindle and is Harmony’s mother (ddbbayat kbrky). She only differs from Wolfie in appearance because to the presence of one brindle gene in the K-Locus. This gives his purple coloring and obvious brindling all around.
The piebald gene is held at the S-Locus. It is a recessive gene so it needs 2 copies for the piebald to be expressed in the dog. For dogs that are dominate in Pied it is written as S/S. For dogs that are carriers of Pied it is written n/S. For dogs that are negative in Pied it is written as n/n.
Napoleon’s mother is one of my favorite women. Belle is a French Bulldog from Southern Utah, and her name is Belle. Ddaya Kyky S/S She is a Blue Fawn who carries two copies of pied balled and carries a “a” at the A-Locus. Because Belle carries two copies of the pieball, which can often cover a significant portion of the dog’s coat, she is referred to as an extreme pieball.
Because the S-Locus requires two copies of pied in order to be expressed on the dog’s coat, Napoleon (ddBbata kyky N/S) only carries one copy of pied. As a result, you cannot perceive any S-Locus expression.
So obviously Fluffy French Bulldogs aren’t a color but let me quickly explain some things that I have been asked about.
- For Fluffies to have long hair, they must have two copies of the Long hair trait. A puppy will be a typical short hair Frenchie if it possesses just one long hair characteristic.
- All colors may be made with fluffier Frenchies, just as they can be made with Frenchies with short hair.
- When evaluated, the long hair qualities of Fluffy have diverse lengths, such as L1, L2, L3, and L4. According to legend, a L4L4 Frenchie will have longer hair than an L1L1 Fluffy, but in my experience, this is simply untrue. I’ve seen L1L1 Fluffies with hair that is same in length to a L4L4 Frenchie. You can also cross an L1L1 fluffy with a L4L4 fluffy to get puppies with very long hair (L1L4).
Here, a French Bulldog with short hair carries one copy of the long hair gene, but long hair is not expressed.
Napoleon is a blue and tan quad carrier (ddCOcoata Ee n/s). We call him a quad carrier because he carries 4 color genes; Blue, Cocoa, Tri and Cream. He carries 2 copies of the blue dilute making his blue, 1 copy of the Cocoa gene at the Co-Locus, is (at/a) at the A-Locus making him a Tri(tan and point). He carries 1 cream gene (E/e) at the E-Locus making his a cream carrier and carries 1 copy of pie-balled (n/s). Since cocoa, cream and pie-balled are recessive you need 2 copies of them at there Locus for them to be expressed on his coat.
Max is a triple-carrier Black and Tan Merle (DdCOcoata Mm). He is (at/a) at the A-locus and carries 1 copy of blue at the D-locus (D/d), 1 copy of cocoa (CO/co), and 1 copy of cocoa. At the M-Locus (M/m), he also has one copy of Merle with him. Merle is a dominant gene, which means that for it to be expressed, only one copy of the gene at the M-Locus is required. The only areas where the merle pattern does not interfere are their tan and point expression (on their cheeks and legs), as well as their whole cream(e/e) coat. This explains why Max’s legs and cheeks are completely hidden by the merle pattern on his body. Blue and Cocoa are recessive; for each of their loci, two copies of the gene are required for expression. He is currently (at/a) the A-Locus. “A gene is the solid black gene at the tan and point gene.” Tan and point are expressed because the tan and point gene “atis dominant over the “a gene.
Having 1 cocoa gene at the Co-Locus and being (ay/AT) at the A-Locus, Ocarina is a blue sable. She would be d/d CO/co ay/at ky/ky in writing. She is a double carrier, making the D-Locus (blue place) where she resides blue. She carries one copy of the chocolate gene at the cocoa locus, but because chocolate is a recessive gene, it is not visible in Ocarina’s coat. She is (ay/at) at the A-Locus, where “ay” is dominant over “at,” which accounts for why she is still blue sable rather than blue and tan with a sold coat. When a dog is sable and carrying one, in some instances “The tan tips may be only barely seen at sight. She lacks the cream, merle, and pied genes, therefore these regions would express (M/M)(E/E)(N/N), but when a dog lacks a certain color gene or pattern, we do not indicate it when we write it out.
Azula is a blue and tan trindle, often known as a blue and tan brindle. This is represented by the letters d/d CO/CO AT/AT kbr/ky. She carries two copies of the blue dilute gene at the blue region, turning her blue. She is B/B because she lacks the chocolate gene. She is blue and tan because she has two copies of the AT gene at the A locus (AT/AT). She possesses a single brindle gene (Kbr), which is dominant over the AT/AT gene and prevents the expression of azula’s blue and tan markings. You can notice some brindling if you look attentively where her Tan Point marks should be.
The color of Harmony is tan and cocoa. She is also referred to as a chocolate and tan trindle in the Frenchie community. She’d be represented by the letters (co/co) (D/d) (at/a)(Kbr/ky). She has two copies of the cocoa gene, which gives her fur the color of cocoa. She possessed a single copy of the blue dilute gene, as well as the tan, point, and the blue dilute gene at the A locus “an (at/a) gene. She also carries one copy of the kbr/ky brindle gene. Harmony doesn’t exhibit the tan and point because she contains the kbr gene, which is dominant over all other loci except when a dog carries two cream genes at the E-Locus.
Napoleon is a Blue and Tans quad carrier (ddCOcoata E/e N/s) and Ocarina is a Blue Sable (ddCOcoayat n/n). At the D-Locus both parents are blue and carry 2 copies of the blue dilute gene so all their pups will carry 2 Blue dilute genes making all their dogs blue. At the Co-Locus (cocoa) both parents are cocoa carriers so they each have a 50% chance to pass it on to their offspring. So on average in a litter of 4 you will have 1 puppy that carries 2 copies of cocoa(co/co), 2 puppies that will carry chocolate (CO/co) and 1 puppy will not carry the cocoa gene (CO/CO). At the A-Locus Napoleon is (at/a) and Ocarina is (ay/at) so since Napoleon had a 50% chance of giving “at or “a to its offspring and Ocarina has a 50% chance of giving the “ay or her “at to her offspring these are all the possibilities for Napoleon and Ocarinas offspring at the A-Locus: (At/At)(Ay/At)(Ay/a)(Ay/At). Remember that (At/at) and (at/a) the dog will express tan and point. In the dogs that are (ay/a) or (ay/at) the dogs will be fawn. When its comes to the cream and pie-balled Napoleon carries 1 gene at each of their Locus and Ocarina does not. So for each of their offspring has a 50/50 chance of acquiring the pie-balled gene and the Cream gene at each of there Locus.
The results of four puppies’ DNA testing from Ocarina and Napoleon’s previous litter are shown below.
Blue fawn quad (ddCOco?aya Ee) describes this female. Since neither Ocarina nor Napoleon are Lilacs, it is unclear if this girl carries cocoa or not, hence the cocoa locus has a question mark. She has a 75% chance of carrying chocolate because both parents carry it. You can also take a look at her because she has a two-to-one probability of having the cocoa gene.
