That's hardly absolute. I have one older sister and one older half-sister, I'm right-handed, and I do not have a twin.[QUOTE="scorch-62"][QUOTE="cobrax55"]If you want absolute proof that its not a choice, its actually pretty easy to show. There are numerous "predictors" for homosexuality, particularly in men. For example, for each older male sibling you have, the chance of you being gay goes up 20%. your also more likely to be gay if you are left handed, or have a twin. All these are related, because they are all related to very early fetal development.cobrax55
Of course its not absolute, rarely in science is anything absolute. Its a cooralation, meaning that one is somehow related to the other. Its not clear why, but having male children changes the ratio of chemicals in the womb in further births. Which apprently can in certain cirmustances effect handiness as well.
The way its thought to work, is that Homosexuality is caused by to much andogen (which is the "male" hormone). Which actually is thought to be why gay men statisticlly have larger penisis and different finger length ratios (which are also controle by andogen)
They have been able to turn animals gay by altering teh amount of chemicals at very precise stages of development, which is how they are fairly certain its true.
You tred on something interesting. How do you feel about research used to show that homosexuality isn't a choice being also used by parents to make the choice for the unborn child by choosing to chemically force a non homosexual child? Those scientists, if correct, have polar opposites wanting success.
