It’s just that’s simple !!!

Boy is this Locus crowded! The four genes held at this location are “Ay” for Fawn, “At” for the tan and point or Tri-color gene, “a” for the solid black gene, and “aw” for sable. “Ay” and “Aw” are very similar and are dominant over, “At” and “a”, making …

The blue locus seems to be everyone’s favorite. A fun fact about the D-Locus is that it is actually just a dilute gene. It dilutes (waters down) the colors that the dogs are in the K- and A-loci. If a dog is a solid black with two blue dilutions, it beco…

This locus works similarly to the D-locus. The CO-locus needs two copies of the cocoa gene in each of its alleles for the cocoa color to be expressed. Cocoa is a testable gene, just like all the others. 

This locus works similarly to the D-locus and CO-locus. The B-locus needs two copies of 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 …

This locus is called the reverse yellow locus, but we know it as cream. Cream is the most dominant gene in the Frenchie color pool if two 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 c…

These are my personal favorites. There are many tricolor variations: black and tan, chocolate and tan, blue and tan, lilac and tan, and merle and tans. What gives these dogs their tan point markings is the allele combination at the A locus. The “At” gene…

This color is a combination of the D-locus (blue) and the B-locus (chocolate) when two copies of each allele are present at each locus (d/d) or at the chocolate locus (blue/b). The coat will usually have a purplish color if the dog carries one or two cop…

The piebald gene is held at the S locus. It is a recessive gene, so it needs two copies for the piebald to be expressed in the dog. For dogs that are dominant in Piedmont, it is written as S/S. For dogs that are carriers of the disease, it is written n/s…

So obviously, fluffy French Bulldogs aren’t a color, but let me quickly explain some things that I have been asked about.

Fluffies need two copies of the trait "long hair" in order to have long hair. If a puppy carries only one long-hair trait, it will…
