STUDY TITLE: Large-scale GWAS reveals insights into the genetic architecture of same-sex sexual behavior
SUMMARY: Identification of novel genetic variants associated with same-sex sexual behavior.
DESCRIPTION: An estimated 2 to 10% of the human population engages in same-sex sexual behavior. While the full spectrum of factors that determine sexual preferences is unknown, some genetic influences exists. This study performed a genome-wide association analysis on over 490,000 individuals of European ancestry. 5 newly discovered genetic variants were associated with nonheterosexual behavior, 2 of which were significant in both sexes. Several of these variants are linked to genes involved in sex-hormone regulation and smell, both of which may factor into sexual attraction.
DID YOU KNOW? Nonheterosexual behavior has become more common, and its acceptance has quadrupled in the past 45 years. [SOURCE]
