In rabbits, black hair is dominant to brown at an autosomal locus, while the sex-linked recessive allele "a" is epistratic to black or brown, causing white fur. A white male was bred twice. Nine bunnies from a black doe were brown or black only. Three bunnies from a doe were black, four were brown, and three were white. What were the genotypes of all three parents? (please show all work and give explanation).
