Which of the following would most quickly be eliminated by natural selection?

B) a harmful recessive allele in a sexual, diploid population
C) a harmful recessive allele in a sexual, polyploid population
D) any harmful allele, regardless of the system of inheritance in a population

Question

Quizplus · Accepted Answer

Harmful alleles in asexual, haploid populations are directly exposed to selection because there is no mechanism, such as dominance or recessiveness, to hide their effects from natural selection. Each individual has only one set of genes, so if a harmful allele is present, it will directly influence the organism's fitness, leading to its quick elimination.
