When individuals of the same species are reproductively isolated, genetic differences may accumulate in sufficient number so that new species could emerge. Such an event would be an example of:Group of answer choicesmicroevolution.the founder effect.equilibrium.speciation.

What process may lead to speciation when a population adapts to its environment, and as an incidental consequence of that, becomes reproductively isolated from other populations?Multiple choice question.Natural selectionPolyploidyA population bottleneckGenetic driftThe founder effect
