As the discipline of genetics changed, so too did the scientific approach to homosexuality. In 2012, scientists examined the possibility that variations in hormone levels in the womb could influence the expression of genes that affect sexual orientation, a line of inquiry that falls under the emerging sub-discipline of epigenetics. The popular media, once so easily convinced by LeVay that homosexuality resulted from brain size and by Hamer that homosexuality was genetic, promptly changed its tune to declare that homosexuality was now epigenetic. Hooray? If it’s hard to get excited about these studies, it’s because, at this point, biological explanations for homosexuality are like iPhones—a new one comes out every year.
The statement ” Based on Chaladze’s calculations,…” from the “Half of all people could be carrying ‘gay genes” story make me think that the study is nought but a statistical analyse, and offers no direct proof that a gay gene exists. Rather give a statistical modal to support the supposition that a gay gene does exist, but that it is so evenly distributed in the population that the Human Genome Project could not find it. I wish that I could have found the study to see the sample size, and the type of analyze none on the group. Here I underline the weasel words:
Half of all people could be carrying ‘gay genes’
Around half of all people, including straight men and women, could carry “gay genes
while straight men may also carry genes predisposing them to being gay
if half of the men and roughly more than half of the women carry genes that predispose men to homosexuality.
Weasel words are “what iffing”,and offers no proof of anything.
