What Is Genetic Drift Quizlet Definition Biology Quiz
Genetic drift is a change in allele frequency due to chance, particularly pronounced in small populations. Genetic drift is the change in frequency of an existing gene variant in the population due to random chance. Genetic drift, also known as random genetic drift, allelic drift or the wright effect, [1] is the change in the frequency of an existing gene variant (allele) in a population due to random chance.
Drift Definition Biology Quizlet Test
Genetic drift is defined as the changing of the number of available alleles in a population by chance events. Genetic drift describes random fluctuations in the numbers of gene variants in a population. It can lead to the loss of genetic variation as alleles may go to fixation or be lost.
