A study to be published in the March 2005 issue of the journal Human Genetics, and available online now, actually undermines the commonly held view that homosexual orientation is determined by genetic factors.
The study’s lead author Brian Mustanski from University of Illinois at Chicago said in a UIC news release that "There is no one 'gay' gene. Sexual orientation is a complex trait, so it's not surprising that we found several DNA regions involved in its expression."
However, a thorough examination of the actual report reveals no statistically significant findings for any of these DNA regions.
The authors describe in the article three non-X chromosomal "new regions of genetic interest” (7q36, 8p12, and 10q26). In the authors’ view, a noteworthy aspect of the study as follows: "Our strongest finding was on 7q36 with a combined mlod score of 3.45 and equal distribution from maternal and paternal allele transmission. This score falls just short of Lander and Kruglyak's (1995) criteria for genomewide significance." They go on to say "two additional regions (8p12 and 10q26) approached the criteria for suggestive linkage" - again pointing out that neither was statistically significant.
Thus, even the author’s “strongest finding” was not statistically significant by widely accepted scientific criteria.
The study also reexamined potential genetic contributions on the X chromosome from region Xq28. This is the region first identified by Dean Hamer as associated with homosexual orientation. However, this study re-analysis, to quote the authors, “did not find linkage to Xq28 in the full sample.” Read More@ http://www.drthrockmorton.com/article.asp?id=128

well duh, just like global warming, it was based on crappy politically enhanced (let's say) "science".....
If both of the parents of a boy were lesbians, will he be gay?
And this surprises who?
You mean... *gasp*... it may actually be a chemical imbalance and not an on/off genetic trait???
What is your point?
the point is that the "science" that alledgedly proved this was true was politcal and not scientific, just like Global Warming.

This is what I thought would happen eventually if not right away. I have always been on the "nurture" side of the aisle. The analogies with a computer are tempting: the speed and memory are built in, but they work with any kind of program.
Even if "Nurture" is actually "Trauma".
Maybe it is actually a choice after all.
School Board Member Asked to Resign After 'Ex-Gay' Reference
Not necessarily.
However it does mean that one of the lesbians is a liar.
"you're back to just a lifestyle choice."
Yup, Christianity is also a lifestyle choice.
Homosexual activity is activity of choice and is not normal behavior.
Anyone with half a brain knows that.
To give someone who indulges in abnormal behavior standing; is ludicrous!
Dueling science or pseudo-science as the case may be?
