Identical Twin Studies prove Homosexuality is not genetic
« on: June 04, 2013, 09:48:34 PM »
So before you start attacking the credibility of the site consider the research being present and peep the sources.  Then also consider that we've been sold a bill of goods on the gay issue. 

Source: http://www.hollanddavis.com/?p=3647

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.”

Bogus science! What does he mean by genetically identical? What does science have to say about that? And finally who is Neil Whitehead? smh  :devil:

Great questions... when you look into this Whitehead cat you come to find out he's been out here on an island by himself with these claims.  As for that the science has to say:

Quote
It is a basic tenet of human biology, taught in grade schools everywhere: Identical twins come from the same fertilized egg and, thus, share identical genetic profiles.

But according to new research, though identical twins share very similar genes, identical they are not. The discovery opens a new understanding of why two people who hail from the same embryo can differ in phenotype, as biologists refer to a person’s physical manifestation...

The scientists examined the genes of 10 pairs of monozygotic, or identical, twins, including 9 pairs in which one twin showed signs of dementia or Parkinson’s disease and the other did not.

Maybe Parkinson's and dementia aren't really genetic after all... right Preacher?

Researchers believe that some of the differences in the appearance and behaviour of identical twins are due to changes in the activation of genes rather than the genes themselves. These are known as epigenetic changes because they change how the genome operates without changing its actual sequence. Our epigenomes therefore refer to the set of unique operating instructions that run each of our genomes' 'hard drive' differently.

I made a major decision today:

I chose not to develop dementia or Parkinson's disease.   ;)
Now faith is being sure of what we hope for and certain of what we do not see.

Dr NE Whitehead, PhD (research scientist)

Author of the book My Genes Made Me Do It - a scientific look at sexual orientation (1999/USA; revised 2nd edition, 2010) and over 140 published scientific papers. The present downloadable edition of My Genes Made Me Do It! takes account of research undertaken between 2000 - 2012, which only strengthens the book's original conclusions. The book takes a position based on an objective, orthodox and extremely comprehensive 20+-year review of more than 10,000 scientific papers and publications on homosexuality. Neil Whitehead: PhD in biochemistry, 1971, New Zealand, employed as a scientist with  the NZ Govt (24 years), the United Nations (4 years), more recently a scientific research consultant. Dr Whitehead has lived and worked in New Zealand, India, the United States, France, Japan and Afghanistan.

Had a big respected 'genius' named Kanazawa write ah article in Psychology Today about how genetically ugly black women are, that science had good backing too......doh mine it was just ah racist madman ranting in ah article

Preacher ah fine yuh movin like dem jihadist when it come to this topic oui.......any chance yuh get yuh postin ah roadside bomb.
