WebThere are five key mechanisms that cause a population, a group of interacting organisms of a single species, to exhibit a change in allele frequency from one generation to the next. These are evolution by: mutation, genetic drift, gene flow, non-random mating, and natural selection. Each mechanism of evolution can be characterized by how it ... WebEvolution refers to a change in the frequencies of different alleles, or gene variants, present for one or more genes in a population of organisms.

POSSIBLE CAUSE OF GENE FLOW AND GENETIC DRIFT

WebGenetic drift. Gene frequencies can change from one generation to another by a process of pure chance known as genetic drift. This occurs because the number of individuals in any population is finite, and thus the frequency of a gene may change in the following generation by accidents of sampling, just as it is possible to get more or fewer ... WebEvery population experiences genetic drift, but small populations feel its effects more strongly.
