Antagonistic Pleiotropy Hypothesis - Benefits and Costs

Benefits and Costs

Antagonistic pleiotropy has several negative consequences. It results in delayed adaptation, an altered path of evolution, and reduced adaptation of other traits. In addition, the overall benefit of alleles is cut down significantly (by about half) by pleiotropy. Still, antagonistic pleiotropy has some evolutionary benefits. In fact, The conservation of genes is directly related to the pleiotropic character of an organism. This implies that genes that control for multiple traits, even if the traits have different implications for the organism's fitness, have more staying power in an evolutionary context.
