Question

All of these population-genetic forces cause allele frequencies to change over time in populations EXCEPT:

Group of answer choices

a) mutation

b) genetic drift

c) migration

d) natural selection

e) random mating

You are studying the population in Iceland for X-linked alleles, and sampling experiments indicate that about 6% of the men have red-green color blindness (caused by a recessive, X-linked allele X^c). Assume that the population in Iceland mates randomly. What is the frequency of the X^c allele in this population?

Group of answer choices

0.36%

3%

6%

12%

36%

Answer 1

Random mating is the answer.

Random mating is the main assumption of Hardy Weinberg equilibrium. The allelic frequency remains constant from generation to generation. If there is found random mating. Whereas mutation, migration, genetic drift and natural selection violates the Hardy Weinberg equilibrium. Hence these factor leads to change the allelic frequency.

6% is the answer.

The 6% of man are color blind. The genotype of man is XcY. The man has one Xc allele. That's why genotypic and allelic frequency are same in man. The allelic frequency of Xc allele is 6%.

please rate high.
