What Color Puppies?

I do not claim to be a DNA expert, but this is what we have been told and from what I have researched it seems valid. Obviously we have the chance of yellow and chocolate pups, however we think there could possibly be black ones in the litter as well. Here is how we understand it: Yellow labs have either pink/brown noses and light color eyes, which DO NOT carry the black gene or they have black noses and eyes, which DO carry the black gene. Kora falls into the second category, so we are hoping for a swirl of color in her litter. Of course true bred labs are solid in color, so when I say “swirl” I do not mean that we expect multi colored puppies. Only time will tell if our theory is correct.
