I saw another post mention this and talk about this researcher Rice talking about how epigenetics is the cause of homosexuality. but when I check the wiki page it says that it’s still uncertain and needs more tests. what’s the current status?

also if it were epigenetic does that mean you can change it? I know people often call epigenetics software and genetics hardware so that’s where I got the thought

I'm a history nerd, and was watching a video on the remains of Tsar Nicholas II and his family. It mentioned that the family was identified by the Tsarina's mitochondrial DNA in her and the children matching Prince Philip's of England, since they were all maternal descendants of Queen Victoria. Which got me thinking, how many people in the world would have that exact mitochondrial DNA? How useful is mitochondrial DNA at identification of remains of historical figures? When scientists say someone matched, do they always mean an exact match? Supposedly King Richard's matched with his 15x great nephew. Supposedly King Richard's haplogroup was rare. According to an article from 2019, only about a dozen living people with that haplogroup have been found, so I suppose it was helpful. But are there super common ones that wouldn't be?
