But absolutely no evidence that it's anything but a choice.
"Homosexuality Is Not Hardwired," Concludes Dr. Francis S. Collins, Head Of The Human Genome Project

April 4, 2007 - Dr. Francis S. Collins, one of the world's leading scientists who works at the cutting edge of DNA, concluded that "there is an inescapable component of heritability to many human behavioral traits. For virtually none of them is heredity ever close to predictive."

How do genes influence behavior?
No single gene determines a particular behavior. Behaviors are complex traits involving multiple genes that are affected by a variety of other factors. This fact often gets overlooked in media reports hyping scientific breakthroughs on gene function, and, unfortunately, this can be very misleading to the public.
Behavioral Genetics
In 2003, the Human Genome Project finished. Since then a genetic predisposition to homosexuality has not been found despite the fact that we know so much about the genome. So in other words, if a scientist pulled ten random people out of a crowd and examined their DNA, scientists would not be able to classify who was homosexual. The only way that one would know who was gay or not was if they shared their sexual history. The use of scientific inquiry is inadequate at identifying homosexual people.
