Which is (are) correct about founder effect?
I. Founder effect occurs when individuals are transplanted to a new location.
II. Founder effect produces new alleles.
III. Founder effect reduces genetic variation.

Question

Quizplus · Accepted Answer

Founder effect occurs when a small group of individuals separates from a larger population and establishes a new population elsewhere. Hence, option I is correct. Founder effect reduces genetic variation because only a small number of individuals carry a subset of genes from the original population, which may not reflect the overall genetic diversity of the original population. Therefore, option III is also correct. However, founder effect does not produce new alleles as the original population is not changed, only a subset of it is taken to a new location. Hence, option II is incorrect.
