If there was complete (100%) selection against an uncommon deleterious recessive genotype (aa) in the human population, would you expect to observe much of an effect on the frequency of the a allele in your lifetime? Why or why not?

Explanation:

Selection is used in identifying some important traits for improving on or elimination.

Selection against is when a selection does not favour a particular allele. If recessive allele is selected against there will be a reduction in the frequency of the allele.

Since it was complete selection against the frequency of the allele will move from its level of fitness to zero and the allele of the gene will be lost completely in the genome of the organism.

natural selection i.e selection done by nature is not enough to get 100% selection against because of the allele reoccuring in heterozygous form but with artificial selection by man it is achievable.
