Question

Genetic Drift and Genetic mutation are responsible for variation, Explain with example.

Answer 1

Genetic drift is a change in allele frequency in a population, due to the forces of chance. Oftentimes, mutations in cells can have no effect. These changes in genetics can increase or decrease in a population, simply due to chance. Although variations of genes (also known as alleles) can be selected for because they help or hinder an organism with reproducing. When the allele is not responsible for the change in its frequency in a population, genetic drift is acting on the allele.
