Results: No single 'gay gene' contributes to same-sex behaviour, study finds!
Published on 09/01/2019
A genetic analysis of almost half a million people has concluded there is no single "gay gene".
The study, published in Science, used data from the UK Biobank and 23andMe, and found some genetic variants associated with same-sex relationships.
But genetic factors accounted for, at most, 25% of same-sex behaviour.
Advocacy group GLAAD said the study confirmed "no conclusive degree to which nature or nurture influenced how a gay or lesbian person behaves."
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 behaviour nor can predict whether someone will be gay.

Many scientists believe that social, cultural, family and other biological factors are also involved, while some religious groups and skeptics consider it a choice or behaviour that can be changed. Which explanation seems more plausible to you? social, cultural, family and other biological factors are involved in homosexual behavior
