Detailed explanation-1: -When individuals with intermediate phenotypes are favoured and extreme phenotypes are selected against, the selection is said to be stabilizing.
Detailed explanation-2: -12.In what type of selection do individuals of average size have greater fitness than small or large individuals?-Stabilizing selection 13.
Detailed explanation-3: -Stabilizing selection selects against individuals with extreme traits and favors individuals with average traits. Stabilizing selection drives the population towards average traits.
Detailed explanation-4: -Stabilizing selection results in a decrease of a population ‘s genetic variance when natural selection favors an average phenotype and selects against extreme variations. In directional selection, a population’s genetic variance shifts toward a new phenotype when exposed to environmental changes.
