In this article, we’ll examine genetic drift, an evolutionary mechanism that produces random (rather than selection-driven) changes in allele frequencies in a population over time.

In particular, genetic drift is more likely in small populations. Examples include the bottleneck effect, where a disaster reduces population size, and the founder effect, where a small group …

But in this video, I wanna talk about a different way in which evolution can take place and this is called genetic drift. So let's find out what genetic drift is.

But in this video, I wanna talk about a different way in which evolution can take place and this is called genetic drift. So let's find out what genetic drift is.

For instance, one gene’s allele frequencies might be modified by both gene flow and genetic drift. For another gene, mutation may produce a new allele, which is then favored (or disfavored) by …

Test your knowledge on selection and genetic drift!

Let’s go back to our lactose tolerance example at the beginning of the article. When multiple environments favor the existence of a trait, these beneficial traits can pop up through mutation …

But in this video, I wanna talk about a different way in which evolution can take place and this is called genetic drift. So let's find out what genetic drift is.

Genetic mutations lead to variations in traits. These variations can provide survival advantages, resulting in new species over generations. For example, brown bears evolved into polar bears …

We’ll examine the factors that cause a population to evolve, including natural selection, genetic drift—random change—and others factors, in the rest of this tutorial.
