How does the founder effect influence the frequency of alleles in a population?
What will be an ideal response?
The alleles carried by the founding population are the only alleles available in the population unless mutation occurs or new individuals migrate to the area. If an allele is not present in the founding population, subsequent generations will not display that trait. For example, if all individuals shipwrecked on an island were blood type O (a recessive trait), all of their descendants would be type O.
