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?

Question

Quizplus · Accepted Answer

The phenotypic ratios of 12/16 pink, 3/16 black, and 1/16 white suggest that the two pink panthers are heterozygous at both loci (AaBb). Using a punnet square, we can see that the only possible genotype for a white panther is aa bb. Therefore, the answer is D (aa bb).
