Detailed explanation-1: -Genetic variations can arise from gene variants (also called mutations) or from a normal process in which genetic material is rearranged as a cell is getting ready to divide (known as genetic recombination). Genetic variations that alter gene activity or protein function can introduce different traits in an organism.
Detailed explanation-2: -Mutation Generates New Alleles Mutation creates slightly different versions of the same genes, called alleles. These small differences in DNA sequence make every individual unique. They account for the variation we see in human hair color, skin color, height, shape, behavior, and susceptibility to disease.
Detailed explanation-3: -The most common sources of genetic variation are germline mutations, gene flow, and sexual reproduction. Germline mutations are important to genetic variation because they occur in gametes and may be passed on to offspring.
