Offspring phenotypes

In guinea pigs, dark coat color (C) is dominant over albino (c), and short hair (S) is dominant over long hair (s). The genes for these two traits show independent assortment. By evaluating the possible crosses, determine the most probable genotypes for the parents of each of these seven crosses: parental phenotypes short dark long dark short albino long albino a)dark short x dark short 89 31 29 11 b)dark short x dark long 18 19 0 0 c)dark short x albino short 20 0 21 0 d)albino short x albi... click for more

Expected genotype and phenotype ratios
