"WebGenetic drift occurs because the alleles in an offspring generation are a random sample of the alleles in the parent generation. Alleles may or may not make it into the next generation due to chance events including mortality of an individual, events affecting finding a mate, and even the events affecting which gametes end up in fertilizations.

WebApr 3, 2024 · The effects of genetic drift on the gene pool can differ with sample size, as in a large population, the loss of an allele due to genetic drift may have a small effect on the overall frequency, but in a small population, the loss of the same allele may result in a much larger change, which can result in the loss of genetic variation in small … WebApr 9, 2024 · Genetic drift stems from the chance occurrence that some individuals in the germ line have more offspring than others. When individuals leave or join the population, allele frequencies can change as a result of gene flow. Mutations to an individual’s DNA may introduce new variation into a population.

WebHere is a quick reminder of how a population evolves by natural selection: Organisms with heritable (genetically determined) features that help them survive and reproduce in a particular environment tend to leave more offspring than their peers.
