A) Random genetic abnormalities
B) Random genetic drift
C) Random mating
D) Natural selection
E) Artificial selection

Question

Quizplus · Accepted Answer

Random genetic drift causes unpredictable changes in allele frequencies due to chance events, such as random mutations or chance fluctuations in reproductive success. This is particularly pronounced in small populations, where chance events can have a greater impact on allele frequencies. Random genetic abnormalities, natural selection, and artificial selection are all forces that can cause predictable changes in allele frequencies, while random mating refers to individuals choosing mates randomly rather than based on specific traits or characteristics.
