Can inbreeding change the gene frequency
WebMay 14, 2024 · Mutation. The frequency of gene B and its allele b will not remain in Hardy-Weinberg equilibrium if the rate of mutation of B-> b (or vice versa) changes. By itself, this type of mutation probably plays only a minor role in evolution; the rates are simply too low.

Can inbreeding change the gene frequency
Did you know?
WebInbreeding does not change the allele frequency within a population, but it does increase the proportion of homozygous individuals to heterozygotes. - Because closely related individuals are more likely to share the same alleles, the chance of two recessive alleles coming together during a mating is high. Web-Note: non-random mating buy itself does not cause evolution but can cause downstream consequences-No allele frequency → phenotype frequency-Against H/W principle (individuals randomly mate)-But can have huge effects and selection can sometime jump in-Inbreeding is most common type:-Reduces offspring fitness (dilitaries recessive) …
WebGenetic purging. Genetic purging is the reduction of the frequency of a deleterious allele, caused by an increased efficiency of natural selection prompted by inbreeding. [1] Purging occurs because many deleterious alleles only express all their harmful effects when homozygous, present in two copies. During inbreeding, as related individuals ...
