Question

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 C produces 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

30 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.

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

PLEASE SHOW STEPS. THANK YOU

Explanation / Answer

frequency of recessive allele is 1/4.

1/4th=0.4 so total population=1.6

30% (0.3) introduced

new population= 1.9

dominant allele frequency=3/4

so dominant allele in next gen=1.9*0.75=1.42
