WebDirectional selection occurs when individuals at one extreme of the phenotypic range have better reproductive success in a particular environment. Can be caused by a mutation that introduces a new allele confers a higher fitness to the individuals that carry it. This favored allele would eventually become predominant in the population. WebJun 12, 2024 · Disruptive selection can lead to a bimodal distribution of trait values and therefore can result in an increase in the variance of a trait without a change in its mean.
