  • Genetic drift (article) | Natural selection | Khan Academy

    khanacademy.org

    https://www.khanacademy.org/science/ap-biology/natural-selection/population-genetics/a/genetic-drift-founder-bottleneck

    WEBGenetic 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.

    WEBGenetic drift, also known as random genetic drift, allelic drift or the Wright effect, is the change in the frequency of an existing gene variant in a population due to random chance. Genetic drift may cause gene variants to disappear completely and …

    WEBJan 15, 2021 · Definition. Genetic drift is a change in allele frequency in a population, due to a random selection of certain genes. Oftentimes, mutations within the DNA can have no effect on the fitness of an organism. These changes in genetics can increase or decrease in a population, simply due to chance.

    WEBGenetic drift, a change in the gene pool of a small population that takes place strictly by chance. Genetic 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 alleles involved.

    WEB6 days ago · 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 …

    WEBIn particular, genetic drift is more likely in small populations. Examples include the bottleneck effect, where a disaster reduces population size, and the founder effect, where a small group starts a new population; both result in less genetic variation.
