Question

What evolutionary phenomenon occurs when a small portion of a population migrates to a new location and becomes founders of a distinct population?

Options

• Bottleneck effect

• Gene flow

• Founder effect

• Genetic drift

Answer 1

The founder effect is an evolutionary phenomenon where a small portion of a population migrates to a new location, causing drastic changes in allele frequencies. The original migrant group becomes the founders of a new, distinct population with altered genetic composition.
