Genetics may have nothing to do with homosexuality.
Or they might have a lot to do with it, we don't know.
Example: The DES (diethyle stilbestrol) daughters.
These girls exhibited a higher incidence of being lesbian than usual for females.
Example: Girls with CAH (congenital adrenal hyperplasia).
These girls experience some degree of masculinization of their genitals and behavior because of an over-active adrenal gland (within the womb). These girls are also much more likely to be lesbian.
How do you know DES and CAH are not caused by genetics, like certain genes the mother might have? How do you know certain genes don't make the mother more likely to have a DES or CAH baby? Is it ever possible to prove that there is no connection at all between DES/CAH and certain genes? Tests like Dr. Hamer's would be useful for finding whatever genes might be associated with those conditions, if there are any.
More research needs to be done on the effects of hormones and drugs on the fetal nervous system.
Sure, I agree completely.
Example: Androgen Insensitivity Syndrome. The XY fetus does not respond to androgens. The result is a female phenotype and female behavior.
Ayup. Jamie Lee Curtis is a MAN, BABY. XY Chromosomes yet everything about her personality and mental makeup is feminine. This gives lie to the idea that XY makes someone a man and XX makes someone a woman and there's nothing else at all.
Doesn't she have a kid?
How do you know Jamie Lee Curtis has XY chromosomes? Isn't that awfully personal information?
