Lower than 0.01%

Explanation:

The human genome has around three (3) billion base pairs long. It has been suggested that the difference among human genomic sequences is around 1 nucleotide change per 1,200 - 1,500 bases, it means that the differences are lower than 0.01%. The nucleotide differences may be due to deleterious mutations, but the vast majority of these differences correspond to neutral mutations
