Answer 4- Chances for A would be 50%.

Answer 5- Since its already 100 % above, so for B its 0%.

Answer 6- From the parent’s phenotypes, we can conclude that male dog is eebb and female is EeBb. So we can make the cross between them and get 50% yellow. Genotypes would be eeB-.

Answer 7- 25% black, with genotype EeBb.
