Coat color is determined by two loci in large cats. two pink panthers fall in love and produce a large litter of baby panthers with the following phenotypic ratios: 12/16 pink; 3/16 black; and 1/16 white. what is the genotype of the white progeny? a) a_ b_b) a_ bbc) aa b_d) aa bb *correct answere) a_ b_ and a_ bb

D) aa bb

Explanation:

Whenever there are two loci involved in a certain trait and after a cross the phenotypic ratio of the offspring is 12:3:1 (instead of the expected 9:3:3:1) there is dominant epistasis, where the presence of a dominant allele in one locus masks the expression of the other locus. In this case, for loci A and B, we could say that the offspring have the following genotypes:

The presence of the dominant allele A in the A/a locus gives pink coat color, regardless of the alleles in the B/b locus.
