Hi. A " discussion"started between two friends of mine about homosexuality.One said that the gene is in there when you are born and comes out in later years. My other friend who is a retired psychiartry ( spelling) nurse argues that it is all in the mind and as was said earlier not in the genes. I tend to agree with my friend about it being your genes but would appreciate any answers

This indicates a potential reason why homosexuality in males persists in the population even though it would be expected to selected against since gay men are less likely to father children.
The genetic connection between siblings can lead to what seem to be counter-intuitive outcomes.
Another factor is the mother's immune system increasingly supressing androgen factors in male foetuses in subsequent pregancies. Consequently her later sons are typically less mascline and more likely to be homosexual.
Compare the masculinity of brothers on average and it is quite obvious.

The early late sons pattern could also be explained by social factors, for example first born sons traditionally carrying the burden of continuing family line and may be more likely to chosea lifestyle that maintains family approval , they may simply be under greater pressure to conform,, later children often have more freedom, I wonder if it is the reverse for women, as most of my gay female friends are first born.
I once read that the lobes of women's brains are slightly further apart than a mans, and the brains of gay men are too - I agree that it is something you're born with. Not so much today as there isn't (quite rightly) any stigma attatched to homosexuality, but for those born when it was classed as illegal, men wouldn't obviously choose it as a lifestyle if they could help it would they?. Incidentally, Lesbianism was never classed as illegal for the simple reason that Queen Victoria refused to believe it happened!!
