What is genetic drift?
a change in the gene pool of a small population due to change.
What is divergent evolution?
when two or more species share a common ancestry become more different over time.
What is gene drift?
random change in allele frequencies that occur in small populations.

What is the bottleneck effect?
Results from drastic reduction in population size. reduces genetic variation.
What is mutation?
causes in genetic variation. 1 in 10,000 cell divisions
the gain or loss of alleles from a population by the movement of individuals into or out of a population.

What is the founder effect?
What is convergent evolution?
the process by which unrelated species become more similar as they adapt to the same kind of environment.
