Detailed explanation-1: -The four factors that can bring about such a change are: natural selection, mutation, random genetic drift, and migration into or out of the population.
Detailed explanation-2: -Genetic drift is a mechanism of evolution in which allele frequencies of a population change over generations due to chance (sampling error). Genetic drift occurs in all populations of non-infinite size, but its effects are strongest in small populations.
Detailed explanation-3: -Germline mutation: A change in a gene that occurs in a parent’s reproductive cells (egg or sperm) that affects the genetic makeup of their child (hereditary).
Detailed explanation-4: -Factors that disturb the natural equilibrium of gene frequencies include mutation, migration (or gene flow), random genetic drift, and natural selection.
