Question

Name the mechanism by which new alleles appear in a population.

Answer 1

●New alleles can be introduced into the population due to the changes introduced out of mutations.

● In addition, the new alleles are introduced into the population by gene flow that occurs in events where there is breeding between two populations that carry unique alleles.

Answer 2

Generally, DNA mutations occurs in germ cells–cells intended to become eggs or sperm.

In this case, the mother cell DNA copied into each new embryo cell after fertilization.

Due to the mutation a new version of the gene are formed called alleles.

These new alleles are introduced into the population.

In addition, the new alleles are introduced by gene flow into the population, which occurs between two populations with unique alleles.
