Question

Explain genetic drift?

Answer 1

Change in allelic frequency in a population

Explanation:

Genetic drift is one of the main parts of evolution, along with natural selection and gene mutation.

Let’s say there’s a family- we have Jack and Jill. If Jack and Jill were to reproduce, they would leave behind the genes previously dropped by Jack and Jill. Essentially, existing genes become dropped or replaced, or even end up becoming much more present than its previous presence.
