Although each of the following has a better chance of influencing gene frequencies in small populations than in large populations, which one most consistently requires a small population as a precondition for its occurrence? mutation nonrandom mating genetic drift natural selection gene flow

Genetic drift

Explanation:

Genetic drift is the process which leads to the drift or shift of the evolving genes from one direction to another and directly affects the evolution.

The genetic drift changes the gene pool of the population is a short period of time due to a sudden event which is not controlled by nature therefore the process is considered a random process.

Since the natural event suddenly changes the gene pool, therefore, the event must act on the small population as the large population cannot be affected by the same natural event at the same time.

Thus, genetic drift takes place in the small population and thus genetic drift is the correct answer.

drift in the gene pool occur due to sudden events therefore the process must take place in tyhe

the answer is true when observing or determining population size, a direct observation is use, in which each organism is counted in a population or in an area. one benefit of this measure is that you get the exact population count but it will take a long time to  determine  the  size  of a  population.
