    Actually there seems to be a good link in the Post "All 3 colours in 1 litter??". I believe it may be on the first page but I'm not sure.

    Ahh, I still don't get it. Not my strong point for sure. My lab is yellow with yellow parents does anyone know what her code would be?

    Are you planning on breeding her? You can test her for chocolate (the b locus) here... Canine Coat Color DNA Testing | VDC for $58. If you don't know for sure what her parents carry (either by test or if they've produced chocolate) than, you'd only be able to guess by pedigree.

    Black is dominant. Chocolate and yellow are recessive so it takes two copies of genes to produce those colors. For example, my male, who is By (black carrying yellow) was bred to a pure chocolate female (Cc). Since my male didn't carry chocolate and the female didn't carry yellow, all 10 puppies were black. All of those puppies will carry the chocolate gene since one parent was chocolate, but only 50% will pick up the yellow gene from the father. Untitled Document It really is fascinating stuff. Remember this is all statistical.

    I bred a yellow to a black and had 3 yellow puppies, even though black is dominant and statistically I should have 50% blacks (carrying yellow) and 50% yellow. So sometimes statistics and genetics like to throw a curveball at you.

    That chart that was posted is the best one out there and we all use it from time to time.

    The only things I know are the following interesting facts (please correct me if I´m wrong):

    1. The only same color breeding that can produce the 3 colors is black mated to black (of course parents need to carry yellow and choco in their blood to be able to do so)
    2. Yellow to yellow will always produce yellow
    3. Yellow to choco should not be done because you get yellow dudley puppies
    4. Lab + Weim = "silver mutt" LOL
    5. Lab + Poodle = Rusty
    6. Lab + Mud = Mess, which = happy lab = angry owner = no matter what color your lab is, it is now chocolate! LOL
