In the Yawncat (A Rare Hypothetical Animal), the Dominant Allele

In the yawncat (a rare hypothetical animal) , 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 the B and b alleles 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 yawncat and a solid brown-tailed female yawncat 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 probability of the next offspring from these same two parents having a spotted brown tail?

A) 1/2
B) 3/16
C) 1/4
D) 1/16
E) 9/16
