number of humans are ambioriented. Handedness shows almost
none for both men and women--McManus: "Measures of handedness
usually show a bimodal distribution with few subjects appearing
truly ambidextrous." Sexual orientation, likewise, shows
almost none for men but a still small though significant number

3There is currently fierce debate
over the existence of a correlation between left-handedness
and certain pathologies, most notably schizophrenia. Some
researchers assert that handedness, thought to reflect one
aspect of brain lateralization, may be a result of a cause--in
some manner a concomitant--of schizophrenia's etiology or
pathophysiology. A study done by Charles Boklage ("Schizophrenia,
brain asymmetry deveopment, and twinning," Biol. Psychiatry
12, 19-35, 1997) powerfully developed the hypothesis, and
Nancy Segal ("Origins and implications of handedness
and relative birth weight for IQ in monozygotic pairs,"
Neuropsychology 27, 549-561, 1989) also supports some form
of correlation. On the other hand, Luchins et al. (1980) and
Lewis et al. (1989), in their respective replication attempts
of Boklage's work, found little support, and Gottesman et
al. ("Handedness in twins with schizophrenia: was Boklage
correct?" Schizophrenia Research 9, 83-85, 1993) conclude
that there does not appear to be an association between handedness
and schizophrenia. (See Gottesman for a more complete bibliography.)
The point, however, is the distinct difference between the
trait profile of handedness and that of sexual orientation:
while there is clinical debate in scientific and research
circles over whether handedness correlates in some way with
psychobiological abnormalities, no such debate exists regarding
sexual orientation, and neither heterosexuality nor homosexuality
are implicated in any mental or physical pathology. [return

'Gay' gene: Fact or fantasy?
In this age, one of the most difficult issues facing our nation
today is the issue of homosexuality. For the most part, homosexuals
become extremely offended if one even suggests that their
sexual orientation was a choice.
Perhaps the greatest defense for the acceptance of homosexuality
is the so-called "gay" gene. While it may not be
easy to "come out" of homosexuality, there is credible
and substantial evidence disproving the "gay"-gene
The first question is, does the issue of whether homosexuality
is a choice, or not, really matter? The Human Rights Campaign,
a homosexual-activist group, doesn't think so. "The vast
majority of gay people will tell you that same-sex orientation
is an innate part of who you are and is not changeable,"
a spokesman said. "But in the final analysis, it really
Whether the sincerity of that statement is valid or not, the
simple fact is that whether homosexuality is a genetic trait
or not does matter. If homosexuality is genetic and not a
choice, then the lifestyle and act must be accepted by everyone,
because it cannot be prevented. However, if it is a choice,
then anyone has the right to label homosexuality unacceptable
The scientific basis the homosexual community uses to prove
the "gay"-gene theory are two different studies
conducted in 1993 and 1995. The studies found a specific marker
in the X chromosome that links to homosexuality in men.
In 1993, biologist Dean Hamer of the National Cancer Institute
found that in 40 pairs of homosexual brothers, 33 of them
had the same set of DNA sequences in a part of the chromosome
This has caused many homosexual leaders to proclaim this "evidence"
and demand respect and acceptance of homosexuality because
of this apparent genetic trait.
However, in late June of 1995, reports were confirmed that
Dean Hamer was being investigated by the Office of Research
Integrity at the Department of Health and Human Services.
Reports found that Hamer may have selectively reported his
research and data – which has led many to question the
credibility of his research.
Furthermore, in the late '90s, a team of researchers at the
University of Western Ontario in Canada found no trace or
evidence of the "gay" gene in homosexual men. The
study found that the region of the X chromosome known as "Xq28"
has nothing to do with the sexual "orientation"
of a person.
Neurologist George Rice studied the DNA of 52 pairs of homosexual
brothers and found that their Xq28 sequences were no more
similar than what might happen from sheer chance.
Despite the debunking of evidence to back the "gay"-gene
theory, homosexual advocates continue to use the out-dated
evidence to promote the existence of a homosexual genetic
Much more evidence can be provided. Identical twins, for instance,
share the same set of chromosomal patterns. Therefore, if
one twin's DNA has a homosexual genetic trait, then it is
inevitable that both twins will be homosexuals. However, that
is not the case with all twins. When one twin is homosexual,
the probability of the other identical twin being homosexual
is 50 percent. Thus, the "gay"-gene theory is, once
again, debunked by using logical, scientific research.
Still, there is even more evidence against homosexual genes.
If homosexuality is, indeed – despite other evidence
– a genetic trait, that gene would eventually be ousted
from the gene pool because homosexuals tend not to reproduce.
Instead, homosexuality has appeared in civilizations across
time. In some parts of the world, homosexuality flourishes,
but in other parts of the world, homosexuality is not present.
Additionally, if "gay"-gene theory were true, it
would be next to impossible to change the lifestyle to heterosexuality.
However, it is not impossible to change sexual orientations
– Stephen Bennett is a great example, and so are the
thousands of others who have come out of homosexuality.
With this incredible load of evidence mounting up against
the "gay"-gene theory, it would be safe to say that
homosexuality is actually not something one is born with,
but a choice.
Instead of using hard evidence and facts, the homosexual community
has stooped so low as to use media to force feed this unproven
theory as fact in order to advance their agenda.
Search for behavioral genes 1993
Study Links Genes to Homosexuality reported the Washington
Post. Is There a Gay Gene? USA Today chimed in.
A self-proclaimed "obscure molecular geneticist,"
Dean Hamer, had conducted a study in the early 1990s that
showed a correlation of a DNA marker on the X chromosome with
homosexual men that was higher than random distribution would
have been. The study had looked at extended family histories
and at the DNA of gay men. Researchers found that a tiny portion
of the X chromosome appeared the same in a surpringly high
proportion of gay brothers. Hamer's team did not find a so-called
gay gene, but found evidence to suggest such a thing existed.
The results were printed in the journal Science in June, 1993,
sparking headlines that ranged from seriousness to tabloid
The article appeared just as President Clinton was pushing
for a new policy of tolerance of homosexual people in the
armed services. What Hamer, and many others, found was the
fact that "the genetics of behavior, and sexuality in
particular, is an emotionally and politically charged topic."
Equally as controversial are discussions of genes for intelligence.
The X chromosome has helped reveal genes linked to intellectual
activity, sparked by the discovery of fragile-X syndrome,
the most common form of mental retardation. After Down's syndrome
it is the most frequently occurring inherited disease among
Westerners. The gene sequence causing fragile-X has been identified,
though not entirely understood. It is not an intelligence
gene, but one that controls fetal development. Down's syndrome,
too, is revealing of the role of genes in development of intellect:
most Down's syndrome children are born with an extra copy
of one chromosome. This difference amounts to less than 2
percent of the chromosome count, but causes gross impairment
of intellect as well as physiological problems. About half
of the 50-100 thousand genes individuals inherit from their
parents are thought to be involved in brain development. But
"nature" is only part of the picture, and its countless
twists, turns, and variations make human development far from
Advances in the understanding of Alzheimer's disease have
helped push discoveries in the relationship of genes and behavior.
As with heart disease, a person may have a gene that predisposes
him or her to develop symptoms. In some cases the symptoms
will occur regardless of behavior, but in most cases there
are environmental or "lifestyle" influences that
spur development of the disease. Eating fatty foods can cause
arteriosclerosis, and drinking lots of aluminum-rich water
can cause buildup of amyloid in the brain, a physical cause
of Alzheimer's dementia.
The genetic link to a homosexuality and the pursuit of knowledge
about each and every human gene has raised ethical and practical
questions about searching for genes for violence or aggression,
shyness, intelligence, and other behaviors.
What is relevant from the debacle of the
Gay gene debate is that either the homosexual lobby who presently
control the heterosexual masses suffer from a genetic defect,
or they are choosing to act unnaturally.
Both the feminist lobby and the gay lobby have taken over.
We want policies that reflect the heterosexual family as the
stable base of society. Those who wish to practice deviant
behaviours such as sadomasochism may do so in private but
please leave the rest of us to enjoy life without witnessing
that which we find repellent.
