Question

Is genetic drift random?

Answer 1

Genetic drift:

1. Genetic drift is the change in the frequency of an existing allele or gene variant in a population.
2. It reduces genetic variation by making some of the gene variants disappear permanently.
3. It causes small-scale microevolution and does not lead to adaptation but creates variations.
4. Its occurrence is sometimes beneficial and sometimes harmful.
5. It leads to changes in allele frequencies which are random in nature.

So, genetic drift is random in nature.
