I don’t play sports professionally, but I do work for a professional sports team. It helped me with the coming out process, and it’s become a big part of my social life as well.”

Both have shown skill in the sport. Clay and I were roommates, and we shared a bathroom in college with our suitemates, and Jack was one of them. And Clay did it in a way so befitting of modern times.

I also made a lot of great friends through LSVA. Furthermore, the model has trouble completely separating the effects of non-shared environment from measurement error, meaning that the large portion of variance attributed to “unique environmental factors” includes many unmeasured or unknown biological and psychological influences.

The development of sexual orientation has long been a subject of scientific inquiry, sparking discussions about biological and environmental influences.

Then, I decided to go to law school at Baylor University, so then it became ‘I’m focusing on my studies.’ About a year or two after graduating from law school, close friends started to ask me if I’m gay. He would get mad if I didn’t bring Jack to our family gatherings.”

Thain and Jack eventually bought a house at 25, got married at 26 when same-sex marriage laws were still rocky — which was attended by Thain’s father — and they eventually married legally five years ago.

For Clay, though, Thain’s newly revealed sexuality put him in a precarious spot.

This involves concordance rates, the percentage of twin pairs where both twins exhibit the same trait.

Insights from Identical Twin Studies

Studies involving identical twins indicate a genetic influence on sexual orientation. Concordance rates for non-heterosexual orientation in identical twins range from approximately 31.6% to 65.8%, with some earlier studies reporting rates as high as 100%.

Sexual orientation is a multi-faceted trait encompassing attraction, behavior, and identity. My social circle right now is formed through volleyball. She talked to the owner, who then talked to me. Evidence supports this, such as studies on women with Congenital Adrenal Hyperplasia (CAH), a genetic condition causing high androgen exposure in utero associated with higher rates of non-heterosexual orientation.

It’s a nice feeling to give careers to people I know are more marginalized that I am as a white, cisgender male. He wanted me to bring Jack, and he wanted to meet him, and it was very positive,” Thain added. Another large study reported that genetics accounted for around 35% of the differences in same-sex behavior among men. There are two primary types of twins:

  1. Monozygotic (Identical) Twins: These twins share nearly 100% of their genetic material as they originate from a single fertilized egg.
  2. Dizygotic (Fraternal) Twins: These twins share approximately 50% of their genetic material, similar to non-twin siblings, as they develop from two separate fertilized eggs.

By comparing the concordance rates of homosexuality between these two groups, researchers can estimate the relative contributions of genetics and environmental factors.

Key Findings in Twin Studies on Homosexuality

Higher Concordance in Identical Twins

Research consistently shows that monozygotic twins are more likely to share a homosexual orientation compared to dizygotic twins.

By comparing individuals with varying degrees of genetic similarity who share a common environment, scientists can generate estimates for the heritability of a trait. Variability in how these dimensions are measured complicates comparisons across studies.

Interplay of Nature and Nurture

While twin studies emphasize the roles of genetics and environment, they cannot pinpoint specific genes or environmental factors.
