When two related species of flowering plants have different structures so that each is pollinated by a different species of insect, what type of reproductive barrier is this?
mechanical isolation
behavioral isolation
temporal isolation
gametic isolation
When a few individuals (whose genetic diversity is probably not the same as the original population) leave a bigger population and go inhabit a new area that is referred to as...
bottleneck effect
founder effect

When a volcano erupts and wipes out a huge area of forest, the few individuals that are left from a large population probably don't have the same genetic diversity as the original population. This is called...

When the intermediate phenotype in a population continues to be favored this is an example of ____ selection.
directional selection
stabilizing selection
