In rabbits, an allelic series helps to determine coat color at the color C locus: 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. What types of progeny would you predict from a cross of Cch x cch

Answer:

1 Full color : 1 Himalayan

Explanation:

This question is depicting the multiple allele phenomenon in rabbits where four different alleles are responsible for coat color. The alleles are:

- C codes for full color

- cch codes for chinchilla; gray color

- ch codes for Himalayan; white with black extremities, and

- c codes for albino; all white

However, according to the question, the order of dominance of these alleles is: C > cch > ch > c. Hence, in a cross between Cch x chc, the following gametes will be produced by each parent:

Cch - C and ch

chc - ch and c

Using these gametes in a punnet square (see attached image), the following genotypic proportion of offsprings will be produced;

Cc = full color

Cch = full color

chc = Himalayan (white with black extremities)

chch = Himalayan (white with black extremities)

Hence, full color and Himalayan are the types of progeny that will be predicted from the cross.
