In a special breed of cats, 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. All genes are unlinked.
A mating between a solid yellow-tailed male cat and a solid brown-tailed female cat 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.
1. The genotype of the female is likely to be:_________
2. The genotype of the male is likely to be: ___________
3. What is the probability of the next offspring from these same two parents having a spotted brown tail? _________
