B)Mutation
C)Genetic drift
D)Natural selection

Question

Quizplus · Accepted Answer

Genetic drift is a random factor that can have a significant impact on small populations due to chance events that can lead to certain gene variants becoming more or less prevalent in the population. In contrast, genetic flow (the movement of genes between populations) and natural selection may be more effective at shaping larger populations over time. Mutation can introduce new genetic variability, but its effects are generally slow and gradual, rather than sudden and dramatic like those of genetic drift.
