WebIn fact, the evolutionary trajectory of a given gene (that is, how its alleles change in frequency in the population across generations) may result from several evolutionary mechanisms acting at once. For instance, one gene’s allele frequencies might be modified by both gene flow and genetic drift. WebApr 10, 2024 · Genetic drift is a mechanism of evolution characterized by random fluctuations in the frequency of a particular version of a gene (allele) in a population. Though it primarily affects small, isolated populations, the effects of genetic drift can be strong, sometimes causing traits to become overwhelmingly frequent or to disappear from a … WebOct 1, 2013 · Even though founder effects lead to a loss of genetic variation, almost every model assumes that founder populations carry levels of genetic variation that are high enough to trigger changes in the nature of epistasis among loci (‘genetic revolutions’, Templeton, 1998; Coyne & Orr, 2004 ). dalton weather net

In each generation, some individuals may, just by chance, leave behind a few more descendants (and genes, of course!) than other individuals. The genes and other genetic elements of the next generation will be those of the "lucky" individuals, not necessarily the healthier or "better"
