Disruptive diversifying selection
WebMay 12, 2024 · Disruptive or diversifying selection is another type of natural selection mechanism responsible for the selection of extreme phenotypes over intermediate phenotypes. And, this type of selection … Disruptive selection, also called diversifying selection, describes changes in population genetics in which extreme values for a trait are favored over intermediate values. In this case, the variance of the trait increases and the population is divided into two distinct groups. In this more individuals acquire peripheral character value at both ends of the distribution curve.

WebDisruptive selection (diversifying selection) favors the two extreme phenotypes of the trait and minimizes the average phenotype. Thus, disruptive selection creates a … WebDiversifying selection is when the variance of a trait in the population increases and even potentially becomes bimodal. ... To think of it another way, disruptive selection would be that an intermediate trait has a lower fitness, but divergent selection would actually mean that the bimodal trait distribution is actually moving in opposite ...
