Why Are People Gay? Gay By Choice or Is Being Gay Genetic?
The term gay is a synonym for homosexual, which is defined as, 1,2 "Of, pertaining to, or exhibiting sexual desire or behavior directed toward a person or persons of one's own sex." In other words, % of people experience same-sex sexual attraction or behavior; of course, this doesn't speak to what makes people gay. Being gay no longer holds the stigma it once did, but in evolution, why does a non-reproductive trait persist? In George Levick, an explorer, travelled to Antarctica. The evolutionary paradox of homosexuality
Scientists may have finally solved the puzzle of what makes a person gay, and how it is passed from parents to their children. Posted August 29, Reviewed by Jessica Schrader. Specifically, many aspects of the development of homosexuality both the male and female varieties are not as well understood as they should be to make some of the claims that many people felt confident expressing. 
What makes someone gay? Science is trying to get it straight.
A new study of nearly , individuals finds that many genes affect same-sex behavior, including newly identified candidates that may regulate smell and sex hormones. Estimates as to the number of gay people in the population range from 1-in to 1-in, so why are some people gay? Are they gay by choice or is being gay genetic?
What causes sexual orientation?
New research shows the genes that make men gay appear to make their mothers and aunts more reproductively successful. While female sexuality appears to be more fluid, research suggests that male gayness is an inborn, unalterable, strongly genetically influenced trait. But considering that the trait discourages the type of sex that leads to procreation — that is, sex with women — and would therefore seem to thwart its own chances of being genetically passed on to the next generation, why are there gay men at all?
Homosexuality may be caused by chemical modifications to DNA
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. That's why some have suggested that epigenetics—instead of or in addition to traditional genetics—might be involved.

In the U. Understanding Homosexuality
For men who identify as gay, their attraction to other men is as natural and unchosen as a heterosexual man’s attraction to women. The question of what causes homosexuality is complex because human sexuality itself is complex. . 
Why Are There Gay Men?
One of the best-established and more intriguing results in homosexuality research is that the more elder brothers a man has, the greater his chances of being gay. The mechanism, only discovered this year, seems to involve each pregnancy leading the mother to develop antibodies against a protein involved in male foetal brain development. .
Stop calling it a choice
Sexual attraction is the romantic or sexual feelings you have toward others. Sexual identity is how you label yourself (for example, using labels such as queer, gay, lesbian, straight, or bisexual). Sexual behavior is who you have sex with and what kinds of sex you like to have. Sometimes all of these things are in line for a person. .
