I'll let you Google it. The Xq28 gene on the X chromosome (which means it is sex-linked) comes to mind.
I guess I should post a disclaimer:
There isn't a single, smoking gun, "gay" gene. But that is to be expected. There are very few things that have a single gene. Most phenotypes are very complex involving anywhere from a few different genes to possibly thousands of genes.
In short, scientists have shown that it is genetically based. They have found a few genes that are statistically linked to being homosexual through twins (both fraternal and identical) who were separated at birth.
I am by no means an expert on this topic, but from the research I have done this is in line with my understanding. Research shows that homosexuality is likely a combination of genetics and other random environmental factors, including fetal hormonal exposure. Not a simple single 'gay gene' answer.
