Random drift

Vedclass · Answer

(D) According to the $Hardy-Weinberg$ principle,allele frequencies in a population are stable and remain constant from generation to generation in the absence of evolutionary forces.$Random \ genetic \ drift$ refers to the change in allele frequencies due to chance events in a small population.Unlike $Selection$ (which is directional),$Mutation$ (which is often directional or specific),or $Migration$ (which introduces specific alleles),$Random \ drift$ causes fluctuations in allele frequencies that are random and non-directional.Therefore,$Random \ drift$ is the factor that brings about a change in gene frequency in a non-directional manner.

In a random mating population in equilibrium,which of the following brings about a change in gene frequency in a non-directional manner?
