Microevolution occurs
A)only when reproductive barriers,either pre- or post-zygotic,prevent all gene flow between two populations.
B)when species diverge.
C)when species populations undergo changes in allele frequencies over time.
D)when reproductive barriers,either pre- or post-zygotic,genetically isolate species to the point where they no longer interbreed to produce viable offspring.

Question

Quizplus · Accepted Answer

Microevolution refers to small-scale changes in the genetic makeup of a population over time. This can occur through various mechanisms, including natural selection, genetic drift, and migration. It does not require the complete isolation of two populations, as some gene flow can still occur. It also does not necessarily lead to the formation of entirely new species (speciation), which is a much more complex process that involves reproductive barriers.
