Genetic architecture of same-sex intimate behavior
One of sets of individuals in the uk Biobank associated on full cousin otherwise nearer [because the acquiesced by genomic resemblance (14); n pairs = 106,979], a whole lot more closely relevant people were expected to become concordant in the terms of same-intercourse sexual behavior. By modeling the fresh communication regarding relatedness certainly one of someone and resemblance of its intimate choices, we projected wider-feel heritability-this new percentage of type from inside the an attribute attributable to genetic version-from the thirty two.4% [95% depend on intervals (CIs), 10.6 to 54.3] (table S4). This guess is actually in keeping with prior estimates away from quicker dual degree (7).
To increase power and generalizability of our results, we also performed a GWAS in the cohort from 23andMe using an equivalent variable (individuals who reported having had sex with “Other sex only” versus the other options on a seven-point scale regarding participants’ sexual partners) (n = 68,527 individuals, of which 12,933 reported same-sex sexual behavior) (table S3) (14). We estimated the genetic correlation (16) between different heritable traits to determine the degree of consistency of genetic influences on same-sex sexual behavior in the two studies, which was high [genetic correlation coefficient (rg) = 0.87; 95% CIs, 0.67 to 1.06] (table S5) (14).
