Detailed explanation-1: -The correct answer is: The founder effect.
Detailed explanation-2: -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-3: -The founder effect is one form of genetic drift. This is the phenomenon in which there is a derivation of a new population from a small isolated group of individuals. The new population is genetically different from the parent populations.
Detailed explanation-4: -The founder effect describes the low genetic variation of a population derived from a small group of individuals in a new geographic location. Genetic drift is the random change of allele frequency in a population.
Detailed explanation-5: -The founder effect is an extreme example of “genetic drift.” Genes occurring at a certain frequency in the larger population will occur at a different frequency–more or less often–in a smaller subset of that population.
