Do you think introversion and extroversion are genetically based ?

I just received an update from ancestry.com indicating that my dna indicates I’m "probably an introvert" (in fact, I am). Curious, considering that my youngest sister, who comes from the same dna source is very much an extrovert and always has been. 🤔

That just tells me the Ancestry is batting 50/50. If they would have checked your younger sis they would have got it wrong.
Are personality traits due to nature or nurture? My guess is the nurture is at least as importan.
