In the guinea pig, one locus that controls coat color may be occupied by any of four alleles: C (full color), c(sepia), c(cream), or ca (albino), with an order of dominance of: C>c>c>c (C is dominant to all other, etc) In the following cross, determine the parental genotypes and predict the phenotypic ratios that would result: sepia x cream, where both guinea pigs had an albino parent
