Homosexual placement in twins: a study on 61 couples and three triplet sets

Abstract

Dual sets through which a minimum of one twin is actually homosexual comprise solicited through reports into the gay click and private referrals from 1980 to the current. An 18-page form in the “sexuality of twins” got filled out by either twins. Thirty-eight pairs of monozygotic twins (34 male frames and 4 feminine couples) happened to be found to get a concordance rate of 65.8percent for homosexual alignment. Twenty-three sets of dizygotic twins are realized to experience a concordance fee of 30.4% for homosexual alignment. Besides, three designs of triplets were received. Two units included a couple of monozygotic twins concordant for erectile alignment on your third triplet dizygotic and discordant for homosexual positioning. A 3rd triplet put got monozygotic with all three concordant for homosexual positioning. These information were viewed as giving support to the discussion for a biological schedule in sex-related orientation.
