Identical twin studies prove homosexuality is not genetic

Eight major studies of identical twins in Australia, the U.S., and Scandinavia during the last two decades all arrive at the same conclusion: gays were not born that way.

“At best genetics is a minor factor,” says Dr. Neil Whitehead, PhD. Whitehead worked for the New Zealand government as a scientific researcher for 24 years, then spent four years working for the United Nations and International Atomic Energy Agency. Most recently, he serves as a consultant to Japanese universities about the effects of radiation exposure. His PhD is in biochemistry and statistics.

Identical twins have the same genes or DNA. They are nurtured in equal prenatal conditions. If homosexuality is caused by genetics or prenatal conditions and one twin is gay, the co-twin should also be gay.

“Because they have identical DNA, it ought to be 100%,” Dr. Whitehead notes. But the studies reveal something else. “If an identical twin has same-sex attraction the chances the co-twin has it are only about 11% for men and 14% for women.”

Because identical twins are always genetically identical, homosexuality cannot be genetically dictated. “No-one is born gay,” he notes. “The predominant things that create homosexuality in one identical twin and not in the other have to be post-birth factors.”

Dr. Whitehead believes same-sex attraction (SSA) is caused by “non-shared factors,” things happening to one twin but not the other, or a personal response to an event by one of the twins and not the other.

For example, one twin might have exposure to pornography or sexual abuse, but not the other. One twin may interpret and respond to their family or classroom environment differently than the other. “These individual and idiosyncratic responses to random events and to common environmental factors predominate,” he says.

The first very large, reliable study of identical twins was conducted in Australia in 1991, followed by a large U.S. study about 1997. Then Australia and the U.S. conducted more twin studies in 2000, followed by several studies in Scandinavia, according to Dr. Whitehead.

“Twin registers are the foundation of modern twin studies. They are now very large, and exist in many countries. A gigantic European twin register with a projected 600,000 members is being organized, but one of the largest in use is in Australia, with more than 25,000 twins on the books.”

A significant twin study among adolescents shows an even weaker genetic correlation. In 2002 Bearman and Brueckner studied tens of thousands of adolescent students in the U.S. The same-sex attraction concordance between identical twins was only 7.7% for males and 5.3% for females—lower than the 11% and 14% in the Australian study by Bailey et al conducted in 2000.

In the identical twin studies, Dr. Whitehead has been struck by how fluid and changeable sexual identity can be.

“Neutral academic surveys show there is substantial change. About half of the homosexual/bisexual population (in a non-therapeutic environment) moves towards heterosexuality over a lifetime. About 3% of the present heterosexual population once firmly believed themselves to be homosexual or bisexual.”

“Sexual orientation is not set in concrete,” he notes.

Even more remarkable, most of the changes occur without counseling or therapy. “These changes are not therapeutically induced, but happen ‘naturally’ in life, some very quickly,” Dr. Whitehead observes. “Most changes in sexual orientation are towards exclusive heterosexuality.”

Numbers of people who have changed towards exclusive heterosexuality are greater than current numbers of bisexuals and homosexuals combined. In other words, ex-gays outnumber actual gays.

The fluidity is even more pronounced among adolescents, as Bearman and Brueckner’s study demonstrated. “They found that from 16 to 17-years-old, if a person had a romantic attraction to the same sex, almost all had switched one year later.”

“The authors were pro-gay and they commented that the only stability was among the heterosexuals, who stayed the same year after year. Adolescents are a special case—generally changing their attractions from year to year.”

Still, many misconceptions persist in the popular culture. Namely, that homosexuality is genetic – so hard-wired into one’s identity that it can’t be changed. “The academics who work in the field are not happy with the portrayals by the media on the subject,” Dr. Whitehead notes. “But they prefer to stick with their academic research and not get involved in the activist side.”

But, but, the liberals have told us that homosexuals are born that way.

That conscience of the music business, “Lady Gaga”, sang a song that they are “Born That Way”.

The liberal view is established, and there’s no science that will change their minds. And we are now compelled to make our social policies, public policy decisions, and public laws, around that idea that homosexuals are “born that way”.

This is a similar liberal concept involved with global warming. Al Gore and his henchmen have declared that the debate is over, the science is settled, etc. on that issue too.

And we may well yet see us make more and more policy decisions in energy and industrial policy based on the idea that global warming is settled science.

And on these issues, among others, if you take issue with the liberals, you will be targeted not for debate of the positions, but for destruction and silencing.

What about that basketball player who came out as homosexual recently? He’s an identical twin, and his twin brother is heterosexual.

“Uh, with me it is.”

Throw in some emotional trauma, lack of morals, drugs and possibly a weak personality and you’d be surprised what can happen.

Today, this is largely a byproduct of boys raised by single moms. The dude in the WH, for example. There are always exceptions, of course.

Maybe you should ask his female fiancé who was with him for 8 years how she feels about his newfound fxg behavior.

I knew a pair of twin brothers in high school who were gay vs straight. It always amazed me that they could be twins, and still have such fundamentally different orientations.

You will NEVER convince libtards that they’re wrong no matter what the evidence is.

I can already hear the response.

“Well, both of the identical twins are gay, but one is just lying because he’s ashamed... and that’s your fault, you conservative bigot!”

He’s speaking in the context of the formative years and how it’s not genetic, I think.

IMO 90% of Homosexuals have had a traumatic sexual experience as a child or a mother or father who pointed them in that direction.

That’s my opinion and I am sticking to it.
I have a niece and nephew both molested by their father and queer as a 3 dollar bill. I remember a child I went to school with whose mother brought him up wearing dresses until he was 10, His mother lived with her husband and a Bull Dyke, Yes, right in the same home. The Lesbian pair down the street both have tales of marriage that went bead.If a person is born queer that person is in the 10% I write off.

Many years ago, before the tyranny of political correctness, James Dobson said that homosexuality resulted from an interruption in the normal pattern of psychological development of a human being.
