Thanks, that's very interesting. Now, a quick question. What about mixed litters where there are yellow, chocolate and black labs in the same litter even if both parents are say, black labs. How does that happen? I've always wondered.

If you don't mind me jumping in!

This is a pretty diagram that shows what dogs that appear to be a particular color can carry as a recessive.

EIGHTY-ONE possible permutations!

No wonder I couldn't do it in my head! (Siamese are much easier!)
