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.
