Description: WebJan 15, 2021 · Definition. Genetic drift is a change in allele frequency in a population, due to a random selection of certain genes. Oftentimes, mutations within the DNA can have no effect on the fitness of an organism. These changes in genetics can increase or decrease in a population, simply due to chance.

Description: WebFeb 23, 2024 · Genetic drift, also known as allelic drift or the Wright effect, refers to the random change in the allele frequency of a particular gene in a population. It is one of the basic mechanisms of evolution with natural selection. Unlike the latter, it does not depend on an allele’s beneficial or harmful effects.

Description: WebGenetic drift is a random effect on biological populations. Its effect is to remove genetic variation from a population of living organisms. [1] In natural populations there are a number of forces acting. There are forces which add heritable variation to the population, such as mutation and recombination. definition
