Does genetic drift work more strongly on large or small populations, and why?

Homework Answers

Answer #1

Organisms in the population constantly adapting their environmental changes. Sometimes a change in enviorment leads to change in allelic frequency of a population, it is known as genetic drift.

Such changes in allelic frequency can be countered easily in large population but in case of small population such changes can't be countered because of small gene pool of that population. Large population have large gene pool which can tolerate such changes easily.

That's why genetic drift works better on small population.
