The survival of a human predisposition for homosexuality can be explained by sexual orientation being a polygenetic trait that is influenced by a number of genes. During development these shift male brain development in the female direction. Inheritance of several such alleles produces homosexuality. Single alleles make for greater sensitivity, empathy, tendermindedness, and kindness. These traits make heterosexual carriers of the genes better fathers and more attractive mates. There is a… 

Sexually Antagonistic Selection in Human Male Homosexuality

This work performs a systematic mathematical analysis of the propagation and equilibrium of the putative genetic factors for male homosexuality in the population, based on the selection equation for one or two diallelic loci and Bayesian statistics for pedigree investigation.

An association between male homosexuality and reproductive success.

Genetic factors predisposing to homosexuality may increase mating success in heterosexuals

Fecundity of Paternal and Maternal Non-Parental Female Relatives of Homosexual and Heterosexual Men

It is suggested that the empirical support for kin selection and maternal effects cannot account for the low universal frequency and stability of the distribution of homosexuals, and data support an X-linked multi-locus sexually antagonistic hypothesis rather than an autosomal multi- locus overdominance hypothesis.

A hypothesis is presented which regards homosexuality neither as an aberration of ‘normal’ human sexuality, i.e. heterosexuality, nor as a ‘defect’, genetically transmitted from parent(s) to

Interfamily Conflict, Reproductive Success, and the Evolution of Male Homosexuality

In a preindustrial context, the mate choices of women are controlled by their parents, who require evidence of wealth and of ability to generate wealth from prospective sons-in-law in order to grant

Homosexual orientation in males: evolutionary and ethological aspects.

The authors examine the combined effects of evolutionary factors and neurohormonal processes on the development of a homosexual orientation and suggests that research into the topic could benefit from an examination of and change in some of the assumptions upon which much past research has been based.

Common genetic factors among sexual orientation, gender nonconformity, and number of sex partners in female twins: implications for the evolution of homosexuality.

Testing the hypothesis that common genetic factors can explain the association between measures of sex typicality, mating success, and homosexuality in a Western (British) sample of female twins found that masculine women are more likely to be nonheterosexual, report more sexual partners, and, when heterosexual, also report moreSexual partners.

Exploring Balanced Polymorphism Theory: Homosexuality, Personality, and Attractiveness

An evolutionary theory known as balanced polymorphism (Hutchinson, 1959), which accounts for the prevalence of the deadly hereditary disease called sickle cell anemia, may prove to be a possible


From the evolutionary point of view homosexual orientation is a puzzle because same-sex sexual preferences significantly reduce individual reproductive success. In this paper, we reconsider two



Neurohormonal functioning and sexual orientation: a theory of homosexuality-heterosexuality.

Evidence indicating that the process of determining human sexual orientation is fundamentally the same in all mammals is reviewed, and a theory of how the entire spectrum of humanSexual orientation is determined is proposed.

A genetic study of male sexual orientation.

Homosexual male probands with monozygotic cotwins, dizygotic cotwins, or adoptive brothers were recruited using homophile publications. Sexual orientation of relatives was assessed either by asking

Correlates and accompaniments of promiscuous sex among male homosexuals.

An empirical exploration of some accompaniments of one dimension of homosexual behavior--having sexual experiences with a large number of partners is undertaken, to differentiate them and understand to what extent the lives of men at the upper end of this continuum are intertwined with other, typically negatively regarded aspects of sexual life.

Sperm competition and the persistence of genes for male homosexuality.

Biodemographic comparisons of homosexual and heterosexual men in the kinsey interview data

Results extended previous findings that, compared with heterosexual controls, homosexual men have a later birth order, an earlier onset of puberty, and a lower body weight.


Results are consistent with the hypothesis that the high birth order of homosexual men reflects the progressive immunization of certain mothers to H-Y antigen by succeeding male fetuses, and the increasing effects of H- Y antibodies on sexual differentiation of the brain in succeeding male Fetuses.

Human sexual orientation has a heritable component.

Family, twin, and adoptee studies indicate that homosexuality and thus heterosexuality run in families, and possible mechanisms that could maintain a balanced polymorphism in human populations are presented.

Birth order and male homosexuality: extension of Slater's index.

Homosexual men tend to be later-born children. Slater's index, the ratio of older sibs to all sibs, is consistently higher for male homosexuals than for comparable heterosexuals. According to some

H-Y antigen and homosexuality in men.

This hypothesis is consistent with a variety of evidence, including the apparent irrelevance of older sisters to the sexual orientation of later-born males, the probable involvement of H-Y antigen in the development of sex-typical traits, and the detrimental effects of immunization of female mice to H- Y antigen on the reproductive performance of subsequent male offspring.

Heritable factors influence sexual orientation in women.

Heritabilities were significant using a wide range of assumptions about both the base rate of homosexuality in the population and ascertainment bias and self-reported history of childhood gender nonconformity.
