A
True.
B
False; the founder effect and population bottlenecks will only decrease the genetic variability if there is no natural selection.
C
False; the founder effect and population bottlenecks will only reduce genetic variation if the population size remains small.
D
False; population bottlenecks will decrease genetic variability, but the founder effect will introduce new genetic variation.
