Answer:
B. There is no genetic drift.
Explanation:
For a population to be in genetic balance it is necessary that, in this population, no genetic drift occurs. This can be explained through the Hardy-Weinberg balance.
According to the Hardy-Weinberg balance, for a population to reach genetic equilibrium, it is necessary that mutations do not occur in this population, natural selection does not occur, does not occur, does not occur gene flow, occurs random crosses and no genetic drift occurs.
Genetic drift is a term used to describe a suture that causes a strong change in the genotype of a population, resulting in a low genetic variability among individuals that will have to undergo selection pressure.
