Question

Genetic drift, given enough time and no other evolutionary forces, will lead to which result?
(a) Increased genetic variation in a population.
(b) Reduced genetic variation in a population
(c) No change in allele frequencies in a population
(d) Hardy – Weinberg equilibrium would be maintained

Answer 1

hey guys your answer is option (d)

Answer 2

Answer: OPTION D

Explanation: Genetic drift is a mechanism of evolution in which allele frequencies of a population change over generations due to chance (sampling error).

Genetic drift occurs in all populations of non-infinite size, but its effects are strongest in small populations.

Genetic drift may result in the loss of some alleles (including beneficial ones) and the fixation, or rise to 100\%100%100, percent frequency, of other alleles.

Genetic drift can have major effects when a population is sharply reduced in size by a natural disaster (bottleneck effect) or when a small group splits off from the main population to found a colony (founder effect).
