Variation in the DNA sequence can result in different alleles or forms of the gene and these individual differences are inherited according to Mendel’s laws of transmission resulting in dominant, recessive, or X-linked forms of inheritance. This variation in the DNA sequence is found about once in every 1,000 nucleotides and as of this writing more than 5 million of these variants are well characterized. The variation occurs in two common forms.
