Is being gay genetic or environmental.
The rationale for excluding homosexuality from the category of sexual deviation category was apparently the lack of evidence that homosexuality per se is a harmful dysfunction. Curiously, the same line of reasoning has not been applied to other “disorders” such as fetishism and consensual sadomasochism.
A genome-wide association study (GWAS) of same-sex sexual behavior reveals five loci and high polygenicity. Follow-up analyses show potential biological pathways; show genetic correlations with various traits; and indicate that sexual preference is a complex, heterogeneous phenotype. Across human societies and in both sexes, …Rahman explains: "Overall, genetics accounted for around 35 per cent of the differences between men in homosexual behaviour and other individual-specific environmental factors (that is, not ...Twin studies suggested, moreover, that gene sequences can't be the full explanation. For example, the identical twin of a gay man, despite having the same genome, only has a 20% to 50% chance of being gay himself.

Massive study finds that genetic markers associated with same-sex encounters might aid reproduction. But some scientists question the ... While research suggests that genetics play an important role in personality, it is also important to recognize that other factors do have an influence. In many cases, the environment influences the expression of genes. Personality tends to be fairly stable, but that doesn't mean it is etched in stone.
Proponents of a choice-based hypothesis cite several potential reasons why an individual might choose to be attracted to someone of the same sex, including ...
GE correlation can be viewed as genetic influence on exposure to environments—literally, a correlation between genetic propensities and experiences. In contrast, GE interaction denotes genetic influence on response to environments, that is, a conditional relationship in which the effect of the environment on a phenotype depends …However, the finding that there's no single gay gene does not mean that sexual orientation is not genetic or biological, and is therefore a lifestyle choice.

AIS is a rare genetic condition whereby androgens do not elicit the intended effect and is a subset of DSD.35 AIS is due to a mutation or deletion in the AR gene, causing an inability of androgens to elicit their effect on tissues pre- and post-birth.36 These individuals will be genetically male but express a female phenotype.

This means that genetic variation has a higher influence on same-sex sexual behavior in men than in …Proponents of a choice-based hypothesis cite several potential reasons why an individual might choose to be attracted to someone of the same sex, including ...As mentioned in Section 12.2, referring to homosexuality as a “puzzle” can be harmful because of historical and, sadly, modern-day human rights abuses towards homosexual people. Biologists don’t use the term “puzzle” to mean that homosexuality is something negative, but that it is an interesting scientific puzzle to study.
The studies have shown that homosexuality has both a heritable and an environmental component. Family studies have shown that homosexual men have more older brothers than heterosexual men.Complex science surrounding genetics and homosexuality. There is no simple dichotomy between genetic and environmental control of a trait, say Brian and Deborah Charlesworth. Richard Gilyead ...Interaction. Contemporary Views. Nature refers to how genetics influence an individual's personality, whereas nurture refers to how their environment (including relationships and experiences) impacts their development. Whether nature or nurture plays a bigger role in personality and development is one of the oldest philosophical debates …Nov 15, 2019 · The interesting thing is how genetics and environment work together. If you think about how much more prevalent same-sex behavior has become lately, people engage in it more than in the past. And that’s clearly not because our genetics are changing. It’s because of the environment, because society is becoming more open and laws are changing.” Most of us believe that we were born that way, but is sexual orientation in our DNA? JV Chamary goes in search of the gay gene
The authors review recent advances and current debates in epigenetics, including how epigenetic mechanisms interact with genetic variation, ageing, disease and the environment.

Abstract. Hypospadias results from a failure of urethral closure in the male phallus and affects 1 in 200–300 boys. It is thought to be due to a combination of genetic and environmental factors. The development of the penis progresses in 2 stages: an initial hormone-independent phase and a secondary hormone-dependent phase.
