Fur color in rabbits is determined by a single gene locus for which there are four alleles. four phenotypes are possible: black, chinchilla (gray color caused by hite hairs with black tips), himalayan (white with black patches on extremities), and white. the black allele (c ) is dominant over other alleles, the chinchilla allele (c^ch) is dominant over himalayan (c^h) and the white allele (c ) is recessive to all others. a) a black rabbit is crossed with a himalayan, and the f1 consists of a ratio of 2 black to 2 chinchilla. can you determine the genotypes of the parents
