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. 🤔

I believe genetics strongly influence personality, but so do other factors. How the parents behave towards others in their social circle, birth order of siblings, family communication styles, school experiences, cultural expression and the neighbourhood all have their effects.
Genes are a complex mix and can recombine in many ways within one family.
