Question

In dragons, the dominant allele R causes solid tail color, and the recessive allele r results in white spots on a colored background. The black coat color allele B is dominant to the brown allele b, but these genes can only be expressed if the animal has an mm genotype at a third gene locus. Animals that are M are yellow regardless of which allele from the B locus is present. A mating between a solid yellow-tailed male dragon and a solid brown-tailed female dragon produces 16 offspring with the following tail phenotypes: six solid yellow, two spotted yellow, three solid black, one spotted black, three solid brown, and one spotted brown. What is the most likely genotype of the male parent? Mm BB Rr MM BB RR Mm Bb RR MM Bb RR Mm Bb Rr
