While this is certainly a topic that can be discussed in good length, I merely want to bring in a tiny bit of my viewpoint: genes aren't everything. (I kinda have to say that as a sociology-student.)
Typically, in such online discussions, I find that there's an almost alarming reliance on hard sciences such as biology, physics or medicine while the only science that will ever be purely logical and completely true is mathematics.
Just how many more "smallest elements" does physics have to define or how often do we have to repaint the illustration of the atom? Why didn't the expensive western-medicine pills that I swallowed for 6 weeks not cure my haemmorhoids and why did the acupressure and homeopathy help?
Science are social fields. There are social fights between actors in the fields to determine what school or what paradigm gets the monopole over the legitimate views that will dominate the field. Those fights more often than not are "dirty", completely dislodged from the apparent "truth" and merely are about cold money such as grants and social status (scientific capital) which we may call scientific reputation or whatever.
Now, what does that have to do with genes? For a researcher researching in the biological field of genetics, of course the cause for everything, the ONLY cause for everything, are the genes. Any other science that has something to say about the topic doesn't matter. The problem is that the hard sciences, with their dynamic of "paradigm-monopoly" and strict rules of scientific approval, often claim to tell "truth" and nothing but and this claim is almost always not questioned by the broader society, largely due to reproduction of the paradigms in schools. In elementary school you learn a small degree of biology, but you hear nothing of sociology, for example, that has a lot of "truths" too. From my perspective, the soft sciences are much more honest than the hard sciences, as in the soft sciences, multiple paradigms are allowed and no one would ever go so far as to claim that their theory should be the only theory allowed in their science. Whereas in physics, for example, there is only one paradigm allowed, paradigms that so far almost always have been either proven wrong or expanded. The problem is that the current paradigms are named "truth" and spread throughout mankind as such and when they are proven wrong, that means that the science lied to everyone for several years. Philosophy, for example, would never be that arrogant.
To me, the hard sciences are merely a basis, an important basis, of course, and, in the creation of science itself, even more important. However, trying to explain or influence such an extremely complicated and complex (social, psychological, theological, philosophical, anthropological, historical, ...) phenomenon as human sexuality with hard sciences alone, in this case biology, is simply negligence. As many of you pointed out already, such a "discovery" could create great social and human problems if the soft sciences don't have a say in the matter. Because, in the end, it is easy to prove that women are inferior to men if the entire scientific field is populated by men (something that in many ways is (still) actual fact). That is of course true for any science, no matter how hard or soft, but with the hard sciences this becomes an actual trouble as they, as mentioned above, claim to know the absolute "truth" while the soft sciences can merely try to convince the rest of the scientific field and the "general population" of a certain paradigm that developed in the science. Example: If philosopyh says that homosexuality is a choice, then philosophy itself will never completely agree on it, as the "other camp" is allowed in the field and the non-philosophers will simply have to check if they believe the paradigm or not. If biology finds out that homosexuality is a choice and the paradigm becomes the dominating one in the field of biology (which is easy to do if biology is full of heterosexuals (something that too in many ways is (still) actual fact) then everyone else will just have to suck it up and believe it, otherwise they are brandmarked as religious fanatics, esoterics, ignorant or whatever. Now you might think that biological scientific discoveries have to undergo a series of criteria involving testing it against "reality" to be named "truth". But as I said before. All sciences are social fields and if Harvard or Oxford or Cambridge finds out that lighting a candle every day makes you gay, then no one will question it. But the discovery that lighting a candle every day makes you gay could just as well be bullcrap, just like the molecule as the smallest element was bollocks.
I guess my point is that you should not overestimate the powers of hard sciences. They very seldomly contribute anything to explain complex phenomenons (such as human sexuality, war, rape, slavery, torment, love, overpopulation, loyalty, trust etc.) and more often than not, the soft sciences have very good answers or explanations for those, but as mentioned twice already, these answers dont claim to be the absolute "truth" but merely are a certain viewpoint derived from a theory by certain individuals, that are named, and not from a theory by certain individuals that are not named but anonymously spread their answers throughout society and history (often with the element of education) in the name of their science.
To put it shorty: Genes? Sure. But can genes really explain why Adam Urtra from Nairobi, who now lives in Barcelona, did not divorce his wife that his parents chose for him even though he knew all these years he was homosexual and, now in Barcelona, with the liberty to divorce and slightly act on his homosexuality, has a secret affair with one of his male co-workers that, under all circumstances, has to remain secret so to not get fired by his boss who regularly attents mass at the local catholic church? I doubt it. But sociology, psychology, theology and (of course as always) philosophy sure can get you quite nice and believable answers to that without trying to break it all down to cold hard scientific "facts" and leave a little dosage of humanity in these answers.

In the end its up to you what you make out of your life. Regardless of environment, raising, or genes you are accountable for your own actions. For better or for worse you hit an age where you can take control of your life and live it the way you want to, or live it the way your told to.
I'm sorry, I just had to pick that one out.

Choice is a luxury. And it's never, ever rational (imo).
