Question

( Evolution )

Recombination typically increases the rate at which adaptation occurs. Why might there be less benefit of recombination in a population that is under strong directional selection and has a low rate of acquiring beneficial mutations? Assume there is little standing variation.

GIVEN QUESTION:-

Recombination typically increases the rate at which adaptation occurs. Why might there be less benefit of recombination in a population that is under strong directional selection and has a low rate of acquiring beneficial mutations?

Ans:-

Where, there be less benefit of recombination in a population that is under strong directional selection and has a low rate of acquiring beneficial mutations then it explained as,follows where,

The Selection requires the selection favoring allele frequency and the phenotype to this phenotype time. However, selection doesn't promote the mutations in the long term. Because, the phenotype might not exhibit the vigor over 15, That is and the inheritance of mutations that are favorable is decreased as soon as it's decreased. That is because the alleles encoding extreme phenotype preferred by directional selection might be dropped because of genetic drift and ends in population decline. Therefore, decreased in diminished population might impact the rate of beneficial mutations.
