Genetic Variation is the range of change in DNA sequence in the genomes of a living species. Although a population of a species will have the same set of genes, it is the the individual Alleles which give the genetic variation.
There are 2 different types of variation classification in populations:
Continuous Discontinuous
In Discontinuous variation, a change in two or more separate forms in a population are called phenotypes
The genetic variation of the sequence/gene is called a mutant, whilst the original sequence is known as the wild type[1].
