Reply to comment by MozeeToby 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

Yea I've always understood genes as being the beginning framework, and then as you grow and develop the little differences along the way is what make the unique human.

I always thought identical twins are the example that very similar genes can still result in very different people....or not. It's all about how the framework grows in it's environment.

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.

Is that why my identical twin is an ugly dofus, and I'm gorgeous beyond compare?

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

See the movie, "Twins" for a true to life perfectly real example of this.
