Reply to comment by Kandiru in When it's said 99.9% of human DNA is the same in all humans, is this referring to only coding DNA or both coding and non-coding DNA combined? by PeanutSalsa

I get that. What I'm curious about is sampling. 90% of which population? Is it 90 of some college-age kids being paid a hundred bucks for a cheek swab? Or is it drawn from a broad swathe of demographics and locations?

The first human reference genome (from the human genome project) was a group of people from all over, random volunteers.
