Incredible. I never thought I would see DNA analysis come so far in my lifetime. I well remember exciting articles in Science Digest magazine in the 1960’s dreaming of what may “some day” become possible “if only human genomes could be mapped.”
I wonder when DNA sequencing will become so cheap that (1) health insurance companies will start paying for it as a tool for diagnosis, and (2) complete sequencing will become routine for newborn babies.
Y-DNA analysis has already allowed me to trace my paternal ancestry to a particular Scottish clan and likely geographical location—and a very interesting migration history.
