What are the genotypes of both parents?

Two unlinked genes affect hair color in mice. CC or Cc mice are agouti. Mice with genotype cc are albino because all pigment production and deposition of pigment in the hair are blocked. At the second locus, the B allele (black agouti coat) is dominant to the b allele (brown agouti coat) A mouse with a black agouti coat is mated with an albino mouse. Half of the offspring are albino, one quarter are black agouti, and one quarter are brown agouti. What are the genotypes of both parents?
