"WebIf the green gene drifts out of the population, and the population ends up in a situation where it would be advantageous to be green, the population is out of luck. Selection cannot increase the frequency of the green gene, because it’s not there for selection to act on. " - Is genetic drift natural selection

WebUnlike natural selection, genetic drift does not depend on an allele’s beneficial or harmful effects. Instead, drift changes allele frequencies purely by chance, as random subsets of individuals (and the gametes of those individuals) are sampled to produce the next generation. WebA. Natural Selection occurs because some alleles confer higher fitness, whereas genetic drift occurs because of sampling error. B. Natural selection has a stronger effect in large population, whereas genetic drift acts primarily in small populations.

In natural populations, genetic drift and natural selection do not act in isolation; both phenomena are always at play, together with mutation and migration. Neutral evolution is the product of both mutation and drift, not of drift alone. Similarly, even when selection overwhelms genetic drift, it can only act on variation that mutation provides. While natural selection has a direction, guiding evolution towards heritable adaptations to the cur…
