Is Sexual Orientation Encoded In Our DNA?

No ‘gay gene’ or genetic signature for same-sex sexual behavior found in the largest human study of its kind

“As a teenager trying to understand myself and understand my sexuality, I looked at the internet for the ‘gay gene’…This paper has basically disproved that.”

— Fah Sathirapongsasuti, Ph.D.




“Genetics is less than half of the story for sexual behavior, but it’s still a very important contributing factor. So, overall, these findings reinforce the importance of diversity as a key aspect of sexual behavior.”

— Benjamin Neale, Ph.D.



“There is no gauge that determines whether someone has a same-sex partner.”

— Andrea Ganna, Ph.D.
