Is it possible to produce a white guinea pig by crossing a homozygous black guinea pig and a heterozygous black guinea pig?

You have one with BB and another with Bb.
You will get all black in the first generation. But if you take two heterozygous black from this group, and cross them, you will get 25% white guineapig.

Let's say..
Black = B
White = b
bb x BB
All offspring will be Bb (Black, heterozygous dominant). Therefore, there is a 0% chance of a white guinea pig.

No, since black is the dominant trait, and you are guaranteed a black allele from the homozygous black guinea pig.
