Question

A mutation that has risen to high frequency through a selective sweep shows a characteristic pattern in which only one allele is found for other loci that occur nearest the selected mutation. Which of the following contribute(s) to this pattern?

Answer 1

Recombination is less likely to separate nearby allele from the favored one contribute(s) to this pattern.

Explanation:

• Selective sweep is the reduction/elimination of the difference in the nucleotide (allele) in the mutation. This usually occurs in a rare allele.

• Mutation is the alteration in the existing gene of a species.

• Recombination is the exchange of DNA between the chromosomes of the parents.

• The mutation levels are prone to increase or decrease during recombination.
