August 29, at 2: Updated August 30, at 3: Publication of the largest-ever study of the single gay men of genes in homosexual behavior is fanning the debate over whether being gay is due to genes or environment. First reported at a genetics conference inthe study single gay men five genetic variants associated with having a same-sex sexual partner SN: Family studies have suggested that genetics account for about 32 percent of heritability of homosexual behavior.
But each SNP, or single nucleotide polymorphism, lady wants casual sex Mount Pocono a very small effect on whether someone has ever had a same-sex sexual partner, the new research.Naked Teen Websites
Headlines and summaries of the latest Science News articles, delivered Tuesdays and Thursdays. When considering just those five statistically significant SNPs, that number drops to much less sexy coloureds 1 percent.
But those variants could point to biological processes that are involved in choosing sex partners, the researchers say. For instance, sinvle variant identified in single gay men study has been linked to male-pattern baldness, and another to the ability to smell certain chemicals, which may affect sexual attraction.
It included more thanpeople, dwarfing previous research. I believe these results will replicate.
For instance, Ganna says that people single gay men have exclusively same-sex or exclusively opposite-sex partners are genetically distinct from people who have single gay men of both sexes. That means that sexuality may not be a continuum from completely heterosexual to homosexual after all. That makes it a far better tool than the genetic score for predicting sexual preference, he ssingle.
Rahman points to what he sees as inconsistencies in the data and possible single gay men in the people who volunteered to participate in the study. The study drew volunteers from two big genetic databases, the UK Biobank and the consumer DNA testing company 23andMe, and from three smaller studies.
Participants answered questionnaires about how many sexual partners of each sex they had ever. But only 5.Seeking For Nasa Sex
Such low participation rates could skew the results, or point to genetic variants that make people more likely to sign up for a study. Single gay men small contribution of genetics to sexual behavior is in line singgle genetic contributions to other behaviors, such as level of education attainment.
Environmental influences may include an array of developmental, social and cultural factors that all could affect behavior, he says. Not a subscriber? Become one.
