What is founder effect ?

The factor that leads to founder effect in a population is:

In terms of gene frequencies, founder effect result in :

(a) How does the Hardy-Wienberg equation explain genetic equilibrium ? (b) Describe how this equilibrium is disturbed that may lead to founder effect.

Define genetic drift. How does it produce founder effect and genetic bottleneck ?

Gene Frequency || Gene Migration (GeneFlow) || Genetic Drift || Founder Effect and Bottleneck Effect || Hardy Weinsbergs Equilibrium
