Consider gene A,which has two (2)alleles in the population.A₄ codes for a mutated allele,which does not produce any protein;the associated phenotype is a disease state that reduces reproductive ability.A₂ is the normal allele and is dominant to the phenotype of A₄;the associated phenotype is not diseased.Based on this information,can natural selection eliminate the A₄ allele?

The A₄ allele can remain in the population because it can be "hidden" in heterozygotes, where the dominant A₂ allele masks its effects.
