Detailed explanation-1: -Genetic variation is the presence of differences in sequences of genes between individual organisms of a species.

Detailed explanation-2: -Genetic variation is a measure of the genetic differences that exist within a population. The genetic variation of an entire species is often called genetic diversity.

Detailed explanation-3: -Variation is the degree by which progeny or offspring differ from their parents. Thse variations could either be genotypic variations (difference in genetic makeup) or phenotypic variations (different traits). Q. The difference that exists between progeny and parents is known as variation.

Detailed explanation-4: -Sexual reproduction results in genetic variation, or genetic differences, between parents and offspring. Offspring inherit one set of chromosomes from each parent. So, an offspring has a mixture of chromosomes (and alleles) from its two parents. Sexual reproduction also results in genetic variation among siblings.

Detailed explanation-5: -Genetic variation is the difference in DNA sequences between individuals within a population. Variation occurs in germ cells i.e. sperm and egg, and also in somatic (all other) cells.
