But if it happens intra-womb it's probably passed on from ancestors. It could also be a minor chromosone alteration which can occur naturally - I think.

That would only apply for those who are exclusively homosexual. Do you ever wonder how some women seem to be attracted to metrosexual types (slick dressers) and even full on gays? In my younger years I found it to be very frustrating. Maybe some fringe homosexual traits have advantages for reproduction.

Do some people become more homosexual at different stages in their lives?

My own view is that it's a mixture of nature and nurture.

There has been some research into birth order and older sibling sex as well, which may support the hormone theory.

That is not necessarily true. Plenty of species, even mammals, have members that do not reproduce, but instead assist with the rearing of the offspring of siblings, parents etc. Given that they share so much in common genetically, they are increasing the liklihood of their genes being passed on by doing so. There are plenty of different strategies that 'work' in a Darwinian sense.

That makes perfect sense. The thought of a straight person suddenly choosing to be gay is totally inane. I can only speak for myself, but my stomach and the rest of my body would revolt at the thought. (eeew)

I disagree Sprint, genetics is far from understood, it is a new science, and the variables are mind boggling, so I certainly would challenge your simplistic interpretation that if the parents aren't gay then the kid can't be, due to his hetero biology.

I have had many gay friends, and I knew some who were raving queens, and others who you would never pick unless they told you, I don't think any of them 'decided' to be gay because they thought it was cool.

You just have to think of your own experiences, do you ever find the sight of a guy sexually arousing?

I know some people can close their eyes, and fantasise about who they would like to be with, and perform sex with someone they do not really find attractive, but they are just deceiving themselves, and whoever they are with, if they do that.

I have known just too many gay people who are not shallow and puerile enough to fake their sexuality, they just choose to accept who they are, and what they are, just as god made them.

Sprint, the original Mendel's experiments prove you wrong.
The same genotype (genetic composition) can produce different phenotypes (outward physical manifestations) thus while homosexual phenotype may not produce offspring heterosexual phenotype may still contain homosexual gene, which is recessive at that particular combination but it will be passed on to a heterosexual's offspring and become dominant in some future generations, e.g if both of heterosexual pair have recessive genes, which recombined may become dominant and manifest itself in homosexual phenotype.

Quote:

IN THE largest ever genetic study of transsexuals, Australian researchers have discovered a DNA variation linked to male-to-female transsexualism.

The finding strengthens the view that there is a biological reason why some people feel they are living in the wrong body, in this case men who have an strong desire to live as a woman.

If it's completely genetic how do you explain previously hetero males whilst in prison taking part in homosexual practices and then when released reverting back to hetero again? Do they undergo some miraculous genetic change?

That's a bit different and easily explained. There are no females in prison.
