Detailed explanation-1: -Genetic variation is defined as the presence of a various number of alleles with different distribution frequencies in a certain population. Genetic variation simply refers to the variation of genomes at the individual level (i.e., between individuals) or at the species level (i.e. between species populations).

Detailed explanation-2: -Individuals of a species have similar characteristics but they are rarely identical, the difference between them is called variation. Genetic variation is a result of subtle differences in our DNA?.

Detailed explanation-3: -Genetic Diversity is the diversity of genetic characteristics (expressed or recessive) within a species (i.e. between individuals and populations of the same species).

Detailed explanation-4: -Genetic Diversity refers to the range of different inherited traits within a species. In a species with high genetic diversity, there would be many individuals with a wide variety of different traits. Genetic diversity is critical for a population to adapt to changing environments.

Detailed explanation-5: -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.
