In rabbits, an allelic series helps to determine coat color: C (full color) , cch (chinchilla; gray color) , ch (Himalayan; white with black extremities) , and c (albino; all white) . The C allele is dominant to all others, cch is dominant to ch and c, ch is dominant to c, and c is recessive to all the other alleles. This dominance hierarchy can be summarized as C > cch > ch > c.
-Indicate the phenotypic ratios expected of rabbits with the cross Cc × chc.
A) 1 full color : 1 chinchilla
B) 1 full color : 1 Himalayan
C) 1 chinchilla : 1 Himalayan
D) 3 full color : 1 chinchilla
E) 2 full color : 1 Himalayan : 1 albino
