Vedclass · Answer

(B) Many genetic disorders are caused by recessive alleles. In a heterozygous state,the individual is a carrier and does not express the disease phenotype,thus the harmful allele is not exposed to natural selection. Because these alleles remain hidden in the gene pool through carriers,they are not eliminated even if they are harmful in the homozygous recessive condition.

Why are some genetic disorders not eliminated from the gene pool despite being harmful?
