genetic drift

Vedclass · Answer

(C) : Genetic drift (also known as the Sewall Wright effect) refers to the random,non-directional change in allele frequencies within a population over successive generations. This phenomenon occurs due to chance events in the sampling of gametes that form the next generation. Because of this random variation in gamete distribution,the allele frequencies in the offspring generation differ from those of the parental generation. Genetic drift is particularly significant and rapid in small populations,where chance events can lead to the fixation or loss of alleles regardless of their adaptive value.

Random unidirectional change in allele frequencies that occurs by chance in all populations and especially in small populations is known as
