A group of scientists suggested tuesday that homosexuals get that. Development of a homosexual preference might have something to do with the maternal environment a male fetus finds itself in. It’s not completely known why someone might be lesbian, gay, straight, or bisexual But research shows that sexual orientation is likely caused partly by biological factors that start before birth People don’t decide who they’re attracted to, and therapy, treatment, or persuasion won’t change a person’s sexual orientation A massive study of half a million people finds no single gene behind sexual orientation, adding more evidence that there is no “gay gene”
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. Homosexuality is romantic attraction, sexual attraction, or sexual behavior between people of the same sex or gender [1][2][3] it also denotes identity based on attraction, related behavior, and community affiliation
