Yep. Just answer the picture. Free points.

I’m going to explain this a little bit because you will see this come up a lot! so the answer has to be A and B. This is because there are to heterozygous parents reproducing. In the picture, the two parents have 75% of their offsprings as black guinea pigs and 25% as white. If the offspring is homozygous dominant (BB) or the same allele, then it is black. If the offspring is heterozygous dominant (Bb) or different alleles, then it is also black because a dominant allele is present. Only one offspring of this combination is homozygous recessive (bb), which means it is the only white offspring. This means that 75% of these guinea pigs’ offsprings are black and 25% are white. Please correct me if i’m wrong and if it’s not a check all that apply question! (and also excuse my sloppy writing in the picture)
