Answers may vary, but should contain the following for full credit:
The origins of sexual orientation are complex, and it is unlikely that a single cause will be identified. Evidence from genetics shows that the likelihood of a gay man's identical twin also being gay is 50 percent; among fraternal twins it is 15 percent. However, likelihoods less than 100 percent indicate that more than genetics must be at work. The fraternal birth-order effect, although intriguing, also leaves room for multiple interpretations. Anatomical differences between the brains of gay and heterosexual men, and gay men and lesbians, have been identified, but these post-mortem studies are open to interpretation as well. Psychodynamic explanations of compromised parenting have been rejected, but clearly there is a role for environmental influences of some kind, given the incompleteness of the genetic evidence. In short, the current answer to the question, "What causes sexual orientation?" is "We don't know."
