Previously, the ridiculous idea of a single 'gay gene
' has been proposed to scientists, stating how this gene is responsible for homosexuality.
The previously theorised "gay gene
" does not exist, a new study has concluded.
THERE is no so-called "gay gene
", but a mix of genetic and non-genetic factors which influence sexual behaviour, scientists have said.
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.
Its authors hope to bury the notion, popularized in the 1990s, of the existence of an all powerful "gay gene
" that determines sexuality in the way eye color is defined.
29, 2019 (HealthDay News) -- There's no such thing as a single "gay gene
" that drives a person's sexual behavior, concludes the largest genetic study ever conducted on the issue.
A large scientific study into the biological basis of sexual behaviour has confirmed there is no single "gay gene
" but that a complex mix of genetics and environment affects whether a person has same-sex sexual partners.
And if being LGBT is rooted in our DNA, then the search for the "gay gene
," however innocuously and scientifically framed, is potentially disastrous for the queer communities.
Previous studies have found tentative genetic links to male sexual orientation, but no "gay gene
" or genes.
The major reason is 'gay gene
' present in a person.
However, scientists have said that they don't know which of the specific genes in the two links of DNA are key to the formation and development of sexual orientation, but said that their findings add to a 1993 study that identified a supposed "gay gene
IN 1993, SCIENTIFIC RESEARCHER and self-identified homosexual Dean Hamer claimed he had found the gay gene
, or rather a gay genetic marker, on the X chromosome at the Xq28 marker.
