What is natural selection in modern terms ? Elucidate the three different effects of natural selection on variation.

Solution

Natural Selection. In modern term, natural selection is differential reproduction. Natural selection is main evolutionary process which causes the change of allele frequencies or in other words, selection is the consistent differences in contribution of various genotypes to the next generation.

If in a population both small and largest individuals contribute relatively fewer offspring to the next generation then those closer to the average size do, stabilizing selection is operating.

If centre of population contributes more, then equilibrium is maintained. While if extremes of population work, then two peaks in the distribution of a trait produced, while former is disruptive selection.
