CHICAGO, IL — (09-01-19) — The largest study of its kind published in Journal Science, found that genetics may explain up to 25% of same-sex behavior but still no evidence of a gay gene.
While new evidence shows genes contribute to same-sex sexual behavior in roughly 25% of LGBTQ sexual behavior, it echoes research that says there are no specific genes that can identify people as gay, bisexual, lesbian or transgender.
New Study Shows 25% of Same-Sex Sexual Behavior Derives from Genetics
The genome-wide research on DNA taken from nearly half a million U.S. and U.K. adults, identified five genetic variants that were not previously linked to same-sex behavior.
Here is the kicker, the variants were more common in people who reported ever having experienced a same-sex sexual experience. That included people whose partners were exclusively of the same sex and those who mostly reported to be heterosexual.
The researchers said…”Thousands more genetic variants likely are involved and interact with factors that aren’t inherited, but that none of them cause the behavior nor can predict whether someone will be gay.” Review the study on Journal Science.
