I retract my previous question for Bella, "Why do you like to lick me so much?" and substitute a geeky question: "Is your beautiful progressive change in coat color from black to silver-grey due to a dominant mutation at the PMEL17 gene? Inquiring minds want to know!" (This is one of the unresolved questions of dog coat color genetics, and I KNOW that Bella would tell me if she could speak, LOL!) |
