Gene flow differs from genetic drift because:
A) it is the random change in the frequency of alleles.
B) it is the random change in a gene or chromosome.
C) it is the guiding force of evolution.
D) it is the spread of new genetic material from one gene pool to another.

Question

Quizplus · Accepted Answer

Gene flow is the movement of genetic material from one population to another, which can introduce new alleles into a population and alter the frequency of existing ones. This differs from genetic drift, which is the random fluctuation of allele frequencies in a population due to chance events. Gene flow can be an important mechanism of evolution as it allows for the exchange of genetic material between populations, potentially leading to the creation of new genetic combinations and adaptations.
