Disruptive selection refers to a type of natural selection that favors individuals at both extremes of a trait’s distribution while disfavoring individuals at the mean. Disruptive selection can create two distinct phenotypic groups and may lead to speciation.
Stabilizing selection, on the other hand, is a type of natural selection that favors individuals with intermediate traits while disfavoring individuals at both ends of a trait’s distribution. This type of selection acts to preserve the status quo and maintain the average phenotype in the population.
In summary, while disruptive selection drives the evolution of new phenotypic groups, stabilizing selection maintains the status quo by favoring individuals with average traits.
