My... to have confidence of THAT calibre. I guess all these psych and genetics courses I'm currently enrolled in have spoiled me.

All jokes about blue denim aside, most of the literature I read for my term paper [which focused on sexual orientation] in Behavioral Genetics class last semester leans toward a cluster of markers on the X chromosome [the Xq28 region, if you care] which appear to be linked to at least one subtype of male sexual orientation.

Good choice of papers, Anders. It's one of my favorites.

Beyond that, they've even managed to divvy up the "sexual orientation" concept into 3 or 4 major subcategories. The commonly held definition is simply the sex (or sexes) I'm attracted to. Cool.

Now, in addition, we also care about the sex(es) which is attracted to ME. Some even mix in _my concept_ of which sex(es) I attract and am attracted to.

Yet Jim up above seems to have it all figured out.

Well, for us bisexuals, this isn't really an issue. But one study I read (which I can't seem to find in my collection of papers from Spring... I might have to go re-look it up) had the scientists manipulating one (and only one) facet of sexual orientation I discussed above. That is, trying to change the sex which likes the fruitfly while keeping the fruitfly attracted to the original sex. I'll get to the details when I can find the friggin' paper. (and it was fruitflies in the study, I wasn't disparaging anyone.)

And to whoever that guy was who wrote this...

We don't all live in a frat house. That's the limitation of your "normal" pattern.
