Genetic Drift is a change in allele frequency's due to ____ Not Fitness
Mutation
Chance
Style
Natural Selection
(a) Genetic drift that results from an event that reduces the size of a population. Some alleles can be lost from the gene pool
Draw an example of bottleneck effect
_____ when a small number of individuals become isolated from the og population and colonize a new area
Bottleneck effect
Founder effect
Hinting effect
Isolation effect
Founder effect: Each new population has a distinct gene pool from the original population resulting in changes in allele frequency which reduces ____
