WebAlthough this example is extreme due to the very small hypothetical population, the same patterns and forces are present in larger – albeit still small – populations. Although the mechanism of the loss of genetic diversity due to inbreeding and drift is different, the effects on populations are the same. 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. frequency, of other alleles.
