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 in rabbits with the cross Cc^ch × Cc^h.

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 in rabbits with the cross Cc^ch × Cc^h.

Quizplus · Accepted Answer

The cross Cc^ch × Cc^h will produce offspring with the following phenotypic ratios:3 full color : 1 chinchilla
