selection and selection tend to reduce the amount of variati

________selection and ________selection tend to reduce the amount of variation in a population, whereas ________selection tends to increase the amount of variation in a population.

Solution

Directional selection and stabilizing selection tend to reduce the amount of variation in a population, whereas disruptive selection tends to increase the amount of variation in a population. The adaptation of a foreign/align species to the newer environment is said to be directional selection. This results in local species desctruction and genetic drift. Disruptive selection increases the variation in an species. This leads to evolution and natural selection. Stabilizing selection acts on the body size of individuals, small ones cannot defend evolutionary changes and large ones can become pray.Thus it leads to reduce the variation among a population.
