A new population forms when a few organisms reach a small island, and its traits become different. Which process can this illustrate?
Answer and explanation
Correct answer: Founder effect
The founder effect is a form of genetic drift that occurs when a new population begins with only a few individuals. The alleles carried by these founders may not represent the frequencies of the original large population, so their descendants can show noticeably different trait frequencies. Thus option A is correct. Analogous organs concern functional similarity, an acquired trait concerns an individual’s lifetime change, and respiration is energy release, so none explains the island population pattern.
