Solutions For An Introduction to Genetic Analysis Chapter 6 Problem 21P

In the multiple-allele series following determines the coat color in rabbits:

• c⁺ encodes agouti.

• c ^ch encodes chinchilla (a beige coat color).

• c^h encodes Himalayan.

The dominance is in the order c⁺>c ^ch >c^h. In a cross of c⁺/ c^h X c^h / c^h, the proportion of progeny will be in chinchilla is:

• ¼ c⁺/c^ch full color.

• ¼ c⁺/c^h full color.

• ¼ c^ch/c^ch chinchilla.

• ¼ c^h/c^h chinchilla

Thus, about 50% of the progeny would be chinchilla.
