Research has shown that homosexuality has a significant genetic component. Studies of identical twins suggest that if one twin is gay, the probability that the other twin will also be gay ranges from 30 to 50 percent. Additionally, studies have found that homosexuals tend to have gay family members, suggesting a genetic link. Being reared by same-sex parents or exposure to sexual abuse does not appear to be consistent predictors of homosexuality. The idea that it is a personal choice made by the individual is also not supported by research.
