Nothing of statistical significance can be said of 44 families. But I personally think that sexual attraction isn't "learned", so when a significant study comes out I expect to see no differences between straight couples.

Scripter has organized them according to date and subject, and there you will learn that it is primarily environmental, including the fact that a large percentage of homosexuals were molested when young.

Actually, I think our pop-culture has proven that it is. Now that we have mass-marketing of beauty, the attractiveness of various body types changes with what's put on the covers of magazines. For a time the Twiggy look was in and very sexy. Playboy reminded us of the value of a C-cup.
It's no different to learn to be attracted to a member of the same sex. That's what makes human beings so unique in the mammal world - we have very few instincts.
Shalom.
