Small populations are _______ likely than large populations to experience evolutionary change based on random events.

Explanation / Answer

Natural selection is the tendency of population to adapt to their environment to enhanace survival. This concept was first proposed by Charles darwin

Mutations or DNA sequence change is the bases for all genetic variability among and within species.

Migration involves either individuals or gametes moving form one population or another therby causing gene flow.

Genetic drift occurs when random events cause changes in genetic compositionof a population. Small populations are less likely than large population to experience evolutionary change based on random events
