Forgive me, I'm just totally ignorant here. In order to sequence your own genome and do something like 23andme, I kinda just guessed that you'd need some kind of existing corpus and database to derive meaning from the results.

Is that true? And if so, is it all open source or free?

It's something that's kind of interesting to me. I really enjoyed biotech and chemistry in HS but ended up going in a different direction. If this is something that you can just get into now as a hobby maybe I'll jump down the rabbithole
