Question

Options

• Founder

• Bohr

• Bottle neck

• Haldane

Answer 1

In bird population of newly formed volcanic island, a rare allele of a gene was noted to be much more prevalent than the populations of same species on the mainland. This is known as founder effect.

Explanation:

Founder Effect occurs when a small group of individuals colonizes a new area (like a volcanic island), leading to a higher frequency of certain rare alleles due to limited genetic variation. This results in genetic differences compared to the original mainland population.
