Genetics Unzipped: Genes, brains and the mind: How much of your personality is encoded in your DNA?

Posted by , on 14 July 2022

Two faces blurring into each other

“A lot of the variation in the big five personality traits is due to genetic differences and there’s suprisingly little effect of the family environment. It seems the way you’re raised doesn’t really affect those particular traits”

Kevin Mitchell, geneticist and neuroscientist

In the latest episode of the Genetics Unzipped podcast, we’re exploring genes, brains and the mind, as we ask how much of our personality is innate, and whether anything we do as adults can change who we fundamentally are. Presenter Dr Sally Le Page sits down with Kevin Mitchell, an Associate Professor of Genetics and Neuroscience at Trinity College Dublin and author of the book Innate: How the wiring of our brains shapes who we are.

Genetics Unzipped is the podcast from The Genetics Society. Full transcript, links and references available online at
