7. In the guinea pig, one locus involved in the control of coat color may be occupied by any of four alleles: C (full color), ck (sepia), cº (cream), or c (albino), with an order of dominance of: C> c> cd > c. In the following crosses, determine the parental genotypes and predict the phenotypic ratios that would result. a) Sepia x cream, where both guinea pigs had an albino parent b) Sepia x cream, where the sepia guinea pig had an albino parent and the cream guinea pig had two sepia parents c) Sepia x cream, where the sepia guinea pig had two full color parents and the cream guinea pig had two sepia parents d) Sepia x cream, where the sepia guinea pig had a full color parent and an albino parent and the cream guinea pig had two full color parents.
