WebIf the assumptions are not met for a gene, the population may evolve for that gene (the gene's allele frequencies may change). Mechanisms of evolution correspond to violations of different Hardy-Weinberg assumptions. They are: mutation, non-random mating, gene flow, finite population size (genetic drift), and natural selection. WebGenetic drift has also a fundamental role in the neutral theory of molecular evolution proposed by the population geneticist Motoo Kimura. In this theory, most of the genetic variation in DNA and protein sequences is explained by a …
Weblecture 8. GENETIC DRIFT. Genetic drift refers to random fluctuations in allele frequencies due to chance events (see figure 6.4, pg. 142). The previous lectures have all dealt with deterministic (predictable) evolutionary forces often referred to as linear pressures. Genetic drift is a stochastic (random) force that can scramble the ... WebGenetic drift can result in genetic traits being lost from a population or becoming widespread in a population without respect to the survival or reproductive value of the …

WebNatural selection, genetic drift, and gene flow are the mechanisms that cause changes in allele frequencies over time. When one or more of these forces are acting in a population, the population ...
