A rabbit breeder has rabbits that exhibit three different coat colors: dark gray, chinchilla (a lighter gray), and albino. When cross breeding rabbits with these different coat colors, he finds that dark gray is dominant to chinchilla and albino, whereas chinchilla is dominant to albino. These phenotypic outcomes indicate that there are more than two alleles of rabbit coat-color genes and that they exhibit

Punnett squares are used to show possible combinations of alleles or to predict the probability of a trait occurring in offspring. a parakeet that is heterozygous for blue feathers (dominant) is crossed with a parakeet that is homozygous for white feathers (recessive). according to the punnett square for this cross, what percentage of offspring is predicted to have blue feathers? 25 percent 50 percent 75 percent 100 percent
