Question

Describe how this equilibrium is disturbed that may lead to the founder effect.

Answer 1

The equilibrium may get disturbed due to genetic drift which may lead to a founder effect. Genetic drift refers to the changes in allele frequencies that occur only by chance events. At times the change in allele frequency can be so different in the new sample of the population, that they can become a different species altogether. The originally drifted population becomes the founder and such an effect is called the founder effect.
