Can I just clear the whole genetics thing up? Most behavioural geneticists (and I have the dubious pleasure of having worked with many of them) are not looking for single genes to contribute to behavioural traits. They look for what is known in the trade as several genes of small effect or for a muliple gene combination that leads to a predisposition to certain things, such as impulsivity, attention span. It is that sort of genetic predisposition that is being talked of in terms of homosexuality, not a single gene.
(Incidently, my family are part of the autism research project in the UK as subjects (they have my genes and I want them back!!- j/k) and there is increasing evidence that there is a high heritability in certain forms of autism.)
Anyway, to study this subject, geneticists do several different types of studies- family, adoption and twin studies, the latter of which give a measure called "Heritability" which gives a sense of the contribution of genes and environment to the behavioural trait in question.
To cut a long boring story short, it is calculated by looking at identical twins and non identical twins and working out whether they share the trait in question.
As identical twins share 100% of their genes and non identical 50% on average, that allows for statistical calculation.
The higher the heritability, the greater the contribution of genes to the condition in question.

I agree, but the evidence is strong that there is a contribution to sexuality from our genes. And there is evidence that more things that cause problems for us have genetic contribution, eg alcoholism, addiciton, anger. Is this new? No! We have accepted for a long time that people have different talents, different difficulties, different crosses to bear. We may not have known why, but phrases such as "he's got his father's temper" are not new...
What worries me about a blanket denial of the evidence about the heritability of sexuality is that if we deny truth because it doesn't fit into our view, all that does is cause others to disregard everything else we say. And it alters nothing. Didn't Jesus himself reminded us in the parable of the talents that is not what we are given that is important, but what we do with it? Those who have been handed a favourable hand via the genetic pool will have much more expected of them!
The good news is, whatever our difficulties, Jesus will carry them with us if we ask him to and He will also give us the grace to overcome them. It is important that those who feel burdened by all this remember that fact.
