Most of the research I run across seems to confirm my own hypotesis about homosexuality: genetics play a substantial, but not exclusive, role in determining sexuality.
Here's one case:
Quote:
A study of twins shows a possible connection between biology and homosexuality.
In a survey of 4,000 people, a research psychologist at the Medical College of Virginia found that a third of the time when one identical twin is gay, the other is also gay.
The researcher, Dr. Kenneth Kendler, told the BBC that his findings do not mean "sexual orientation (is) genetically determined, but clearly genes are playing some role by interacting with a range of environmental factors."
The study included 794 pairs of twins of which 40 percent were identical twins. The researchers said their findings indicated that a greater percentage of identical twins included two gays in the pair compared to non-identical twins. Among non-identical twins, 8.3 percent were both gay, but with identical twins 31.6 percent were both gay.
Kendler said he recognized that the study sample was small, but nonetheless, "we were finding something that was moderately inheritable," he said.

here is a decent an undergrad paper on the subject
Now your turn.
