In addition to this, the human genome serves as a reference genome. You don't need to say "this patient has this string of 500 base pairs representing their variant" you can just say "at position 125 they have a GTA instead of ATA and at 244 they have 6 duplicated pairs"

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.
