RE: Homosexuality: it's genetic expression, not genetics, that determines homosexuality

Quote:Writing in The Quarterly Review of Biology, researchers William Rice, a professor at the University of California, Santa Barbara, and Urban Friberg, a professor at Uppsala University in Sweden, believe that homosexuality can be explained by the presence of epi-marks — temporary switches that control how our genes are expressed during gestation and after we're born.
Specifically, the researchers discovered sex-specific epi-marks which, unlike most genetic switches, get passed down from father to daughter or mother to son. Most epi-marks don't normally pass between generations and are essentially "erased." Rice and Friberg say this explains why homosexuality appears to run in families, yet has no real genetic underpinning.
I guess one can still fit this into the category of genetics then.
And I really dont hink that there is any such thing as "the one final explaination for sexual orientation".
A persons sexuality is just as influenced by his or her genes as by his or her surroundings.
Meaning, a person doesn`t get it`s sexuality handed over like car keys when it reaches puperty.
Just like person isn`t handed over it`s personality when it reaches adulthood at the age of 18.
Frankly: A persons sexuality also evolves out of that persons expiriences and out of the social\psychological influences under which that person stands. - Not only out of the genes it carries.
