Problem:

In a population of desert bighorn sheep, a mutant recessive allele c has been found to cause curled coats in both males and females. The normal dominant allele Cproduces straight coats. The frequency of the mutant recessive allele c has been determined to be 0.4.

Biologists, in an effort to increase genetic diversity in the bighorn sheep population, introduced sheep from a population in a different region where the c mutation is absent. These introduced sheep comprise of 10 percent of the parents of the next generation. Assume that random mating occurs between the original and the introduced sheep, and that the c allele is selectively neutral.

Question: What will be the frequency of normal dominant allele C in the next generation?

Recall that the equation for determining the impact of immigration on the gene pool of an existing population is estimated by the following equation:

pi?=(1?m)pi+mpm

where m represents migrants.

Round your answer to two decimal places.
