Well, there's almost no doubt that if homosexuality is genetic, it is more complicated than a single gene locus.
There was a landmark study released last week that said humans are much more genetically different from one another than previously thought.
The study demonstrated, that apart from having gene by gene differences there is actually much more variation in the number of copies of each gene called CNVRs (copy number variations). Estimates that instead of 1% variability between individuals there's 12%!
What this means, is that looking for a specific gene might be a mistake, they should be looking at specific genes AND how many copies there are of it. It is highly likely that many diseases, and behavioural characteristics will at some stage be explained by this.
