Genetics help shape your personality, and those same genes reverberate throughout your life. Researchers found that more than 1,200 different genetic variants are linked to personality traits. What’s more, those personality genetics are linked to dozens of different paths taken throughout a person’s life, including health, education, career and parenthood. There’s no single personality gene, but personality traits are associated with many genetic variants. Further, they found that the genetic variants that predict personality also partially predict a person’s mental or physical health, longevity, education, career path and decision to become a parent, among other things.
