Epigenesis was getting more focus about 5-10 years ago, I think, but with the advent of advanced genetics and molecular biology, sadly, people are being seduced by genetic explanations for all sorts of things.
Undoubtedly.
But, y'see, the problem with these "genetics-only" expanations is that if the gene (or genes) in question doesn't have a species-typical environment to "flow" itself into, it will be incapable of producing the trait associated with it.
Look at it this way: gene A only produces effect or trait B when supported by environment C. If, for example, I put gene A in environment D instead, a totally different effect could result --- including no effect at all (i.e., biological death). This is why the results of our particular genetics are explicitly rooted in evolution via natural selection, in which we have developed species-typical adaptations to counter species-typical environments (whether they be prenatal, perinatal, natal, postnatal, or social). That's just the way it is.
Likewise, the opposite is true: the information from environment C will have no significance unless there is gene A for it to "flow" into. If we were to hypothetically replace gene A with, say, gene B while in the same environment (C), a totally different interactionist result could emerge.
As I said before, the system is bi-directional. It flows both ways.

Nice comment on the species-typical environments, BTW. Some reseach has been looking at environmental inheritance - i.e. what offspring inherit from their parents, in terms of their local environment(s). V. interesting.
Well, that's how the ideas were taught to me.

Aside from that, I think some of the biggest proponents of the "homosexuality is (most, all, very) genetic" are gay rights fans, who are looking for an explanation that will get fundies off their backs. I can understand why that would happen.
This is understandable, of course.
However, as I once said to a friend, people really need to stop trying to collapse the science and morality issues here. They're two pretty damn distinct modes of inquiry (albeit there can be some interesting correlations here or there).
A particular trait (not even necessarily sexuality) could be 'natural' (as in, predisposed at birth). But, this does not necessarily mean it is 'right' or 'proper' (if you choose to accept such terminology) one way or another. Most forms of schizophrenia, for example, are genetically inherited.
Likewise, a particular trait could be 'nurtured' (as in, the result of environmental and/or social influences). But, this does not necessarily mean it is 'wrong' or 'unnatural', either. Most forms of what we would consider 'compassion', for example, are learned behaviors. Manners, at the very least, are learned behaviors.
So, as I said, the whole science and morality of the issue here don't really coincide at all. People need to stop trying to use science to 'prove' homosexuality is 'right' or 'wrong', either way. Its not what science is for.
