    Of course there is a genetic component. However, as you say there is a "statistically significant increased chance of being homosexual". An increased chance doesn't mean inevitability. And the chance for identical twins is 20% so likely to be lower for brothers. The environment is without doubt a large contributing factor and the genetic component is yet to be sufficiently identified todate.

    "If I provide the studies, will you accept them?" Why would I accept the results of studies which someone I don't know from the internet? Who has conducted these studies? Have they been replicated? Where is the analysis across all the many studies which have been done because this would have been performed as well. How highly regarded are those who have conducted these studies. If they are funded by the gay rights people, are they reliable? Of course not.

    To date, the only evidence which exists is that genetics is indeed a component but absolutely nowhere near the full story. 20% of identical twins are similar in their sexual identities. Many change their sexual preferences within the adult lives, so the idea that sexuality is set in concrete at birth is nonsense.

    The difficulty with citing that "younger brothers have a statistically significant increased chance of being homosexual. This effect is *only* observed if they're biological brothers" is these brothers are also likely to have been brought up in the same environment, so there can still be the environment which is affecting them rather than genetics being the determining factor. This is why studies of identical twins where one twin lives away from the other (as in different childhoods with different carers) is a more reliable way of identify genetically determined behaviour. Researchers endeavour to use these identical twins (as opposed to many twins who are identical) who have been separated at birth because they are more valuable in researching psychological traits which are likely to be due to genetics. Brothers, by the way, do not share the same genetic structure although likely to share the same environment, so your "You work it out" comment has little value. But you've never studies psychology now, have you? I have.
