Detailed explanation-1: -The founder effect occurs when a small subgroup of a population decides to migrate from one place to another. As a result, there are now changes in their allele frequencies that are different from the original species.
Detailed explanation-2: -The founder effect occurs when allele frequencies change as a result of the migration of a small subgroup of a population. Two groups from a large, diverse population could produce new populations that differ from the original group.
Detailed explanation-3: -Genetic 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.
Detailed explanation-4: -Definition. A founder effect, as related to genetics, refers to the reduction in genomic variability that occurs when a small group of individuals becomes separated from a larger population.
Detailed explanation-5: -(FOWN-der myoo-TAY-shun) A genetic alteration observed with high frequency in a group that is or was geographically or culturally isolated, in which one or more of the ancestors was a carrier of the altered gene.
