Question

A change in the genetic makeup of a population is one of the mechanisms of evolution. Match the different forces of genetic change to the correct examples.

Answer 1

1. Founder effect

2: Bottleneck effect

3: Mutation

4: Gene flow

Step-by-step explanation:

Change in the gene frequency of the population when few members of a population colonize a new area is called as founder effect. When any adverse environmental conditions such as disease or natural disaster reduce the population size and cause genetic drift, the process is called as bottleneck effect. Any random changes in genome of organisms are called as mutations. Gene flow refers to exchange of alleles between local populations as caused by migration of individuals to the new habitat.
