B)migration
C)splicing event
D)genetic drift

Question

Quizplus · Accepted Answer

Genetic drift is a random fluctuation in the frequency of alleles in a population, which can cause a change in the gene pool from one generation to the next. This can occur due to chance events such as natural disasters, random mating, or the loss of individuals from a population. Mutations can also lead to changes in the gene pool, but they are not necessarily due to chance or accident. Migration refers to the movement of individuals from one population to another, which can introduce new alleles but is not necessarily random. Splicing events refer to the rearrangement of genetic material within a single individual, rather than changes in the frequency of alleles across a population.
