on a physiological cause for homosexuality. Twins studies would seem to rule that out. The incidence of h. in identical twins (where one is afflicted with h and the other is not) is lower than in fraternal twins and lower than in non-twin siblings.
Even though identical twins have the same physiology they have different rates of h.
(Scripter, do you recall the exact study this came from. I think it was the Hamer twin study but it’s been so long since I looked at it I may be wrong. Thanks!)
I never said physiological cause. Just component. Twin studies won’t entirely rule that out. Identical DNA doesn’t mean that all other biological processes track exactly the same as the subjects advance in age.
