In rabbits, an allelic series helps to determine coat color: C (full color) , c^ch (chinchilla; gray color) , c^h (Himalayan; white with black extremities) , and c (albino; all white) . The C allele is dominant to all others, c^ch is dominant to c^h and c, c^h is dominant to c, and c is recessive to all the other alleles. This dominance hierarchy can be summarized as C > c^ch> c^h> c.
-Indicate the phenotypic ratios expected of rabbits with the cross Cc^h × c^hc.

The cross Cc^h × c^hc results in offspring with genotypes: Cc^h, Cc, c^hc^h, and c^hc. The phenotypes are 1 full color (Cc^h and Cc) and 1 Himalayan (c^hc^h and c^hc).
