But geneticists have had only a handful of underpowered studies to address a complex, fraught, and often stigmatized area of human behavior. Now, the largest-ever study of the genetics of sexual orientation has revealed four genetic variants strongly associated with what the researchers call nonheterosexual behavior. Some geneticists are hailing the findings as a cautious but significant step in understanding the role of genes in sexuality. Others question the wisdom of asking the question in the first place. Andrea Ganna, a research fellow with the Broad Institute in Cambridge, Massachusetts, and Harvard Medical School in Boston, and colleagues examined data from hundreds of thousands of people who provided both DNA and behavioral information to two large genetic surveys, the UK Biobank study and the private genetics firm 23andMe. The researchers performed a genome-wide association study GWAS in which they looked for specific variations in DNA that were more common in people who reported at least one same-sex sexual experience.

Many Genes Influence Same-Sex Sexuality, Not a Single ‘Gay Gene’
10 Anti-Gay Myths Debunked | Southern Poverty Law Center
Battling the 'homosexual agenda,' the hard-line religious right has made a series of incendiary claims. But they're just not true. Ever since born-again singer and orange juice pitchwoman Anita Bryant helped kick off the contemporary anti-gay movement some 40 years ago, hard-line elements of the religious right have been searching for ways to demonize gay people — or, at a minimum, to find arguments that will prevent their normalization in society. For the former Florida beauty queen and her Save Our Children group, it was the alleged plans of gay men and lesbians to "recruit" in schools that provided the fodder for their crusade. But in addition to hawking that myth, the legions of anti-gay activists who followed have added a panoply of others, ranging from the extremely doubtful claim that sexual orientation is a choice, to unalloyed lies like the claims that gay men molest children far more than heterosexuals or that hate crime laws will lead to the legalization of bestiality and necrophilia.

The American Psychiatric Association and the American Psychological Association have suggested for many years now that there is significant empirical evidence supporting the claim that homosexuality is a normal variant of human sexual orientation as opposed to a mental disorder. This paper summarizes and analyzes that purported scientific evidence and explains that much if not all of the evidence is irrelevant and does not support the homosexuality-is-not-a-mental-disorder claim. As a result of their deficiencies and arbitrariness, the credibility those two groups that are typically deemed authoritative and trustworthy is called into question.
