簡介In their Research Article “Large-scale GWAS reveals insights into the genetic architecture of same-sex sexual behavior”, A. Ganna et al. found that prevalence of same-sex experience in the UK Biobank population increased four-fold across study participants’ birth years, and prevalence in the younger, self-selecting 23andMe consumer population was 6 times that of UK Biobank. The authors treat single nucleotide polymorphisms identified in these populations as ahistorical components of the “architecture of same-sex sexual behavior.” We question the generalizability of their findings. Political context and stigmatization of homosexuality affects whether people engage in and/or report same-sex behavior. Historical conditions such as decriminalization of homosexuality in 1967 and legalization of marriage equality in 2013 and 2014 instigated substantial shifts in reporting of same-sex orientations.

簡介Since the early 1990s, researchers have shown that homosexuality is more common in brothers and relatives on the same maternal line, and a genetic factor is taken to be the cause. But since gay and lesbian people have fewer children than straight people, a problem arises: “How can a trait like male homosexuality, which has a genetic component, persist over evolutionary time if the individuals that carry the genes associated with that trait are not reproducing?”
