Reply to comment by BeardOBlasty in If the Human Genome Project represents a map of the genome of a few individuals, why is this relevant to humans as a whole if everybody has different genetics? by bjardd

Identical twins will not have the exact same DNA at every point in each of their chromosomes. Each a cell divides, including the division which resulted in twinning, some number of mutations are likely to occur.

That's correct, the genes for beauty disproportionately went to you, unfortunately, the genes for intelligence might have gone the other way. Only kidding!!! :)
