"GOD CREATED SOME OF US GAY" - A scientific analysis of homosexuality and the 'Gay gene' (PT.1)

"This is the Way God Made Me"--A Scientific Examination of Homosexuality and the "Gay Gene"

The trumpets were left at home and the parades were canceled. The press releases and campaign signs were quietly forgotten. The news was big, but it did not contain what some had hoped for. On April 14, 2003, the International Human Genome Consortium announced the successful completion of the Human Genome Project—two years ahead of schedule. The press report read: “The human genome is complete and the Human Genome Project is over” (see “Human Genome Report...,” 2003, emp. added). Most of the major science journals reported on the progress in the field of genetics, but also speculated on how the information would now be used. The one piece of information that never materialized from the Human Genome Project was the identification of the so-called “gay gene.”
Homosexuality has been practiced for thousands of years. Simply put, homosexuality is defined as sexual relations between like genders (i.e., two males or two females). It was Sigmund Freud who first postulated that parental relationships with a child ultimately determine the youngster’s sexual orientation. But this “nurturing” aspect has effectively given way to the “nature” side of the equation. Can some behaviors (e.g., alcoholism, homosexuality, schizophrenia) be explained by genetics? Are these and other behaviors influenced by nature or by nurture? Are they inborn or learned? Some individuals believed that the answer would be found hiding amidst the chromosomes analyzed in the Human Genome Project.
The human X and Y chromosomes (the two “sex” chromosomes) have been completely sequenced. Thanks to work carried out by labs all across the globe, we know that the X chromosome contains 153 million base pairs, and harbors a total of 1168 genes (see NCBI, 2004). The National Center for Biotechnology Information reports that the Y chromosome—which is much smaller—contains “only” 50 million base pairs, and is estimated to contain a mere 251 genes. Educational institutions such as Baylor University, the Max Planck Institute, the Sanger Institute, Washington University in St. Louis, and others have spent countless hours and millions of research dollars analyzing these unique chromosomes. As the data began to pour in, they allowed scientists to construct gene maps—using actual sequences from the Human Genome Project. And yet, neither the map for the X nor the Y chromosome contains any “gay gene.”
What is the truth regarding homosexuality? Too often, speculation, emotions, and politics play a major role in its assessment. The following is a scientific investigation of human homosexuality.


In an effort to affect public policy and gain acceptance, the assertion often is made that homosexuals deserve equal rights just as other minority groups—and should not be punished for, or forbidden from, expressing their homosexuality. The fight for the acceptance of homosexuality often is compared to “civil rights” movements of racial minorities. Due to America’s failure to settle fully the civil rights issue (i.e., full and equal citizenship of racial minorities), social liberals, feminists, and homosexual activists were provided with the perfect “coat tail” to ride to advance their agenda. Using this camouflage of innate civil liberties, homosexual activists were able to divert attention away from the behavior, and focus it on the “rights.”
The argument goes like this: “Just as a person cannot help being black, female, or Asian, I cannot help being homosexual. We were all born this way, and as such we should be treated equally.” However, this argument fails to comprehend the true “civil rights” movements. The law already protects the civil rights of everyone—black, white, male, female, homosexual, or heterosexual. Homosexuals enjoy the same civil rights everyone else does. The contention arises when specific laws deprive all citizens of certain behaviors (e.g., sodomy, etc.). We should keep in mind that these laws are the same for all members of society. Because of certain deprivations, homosexuals feel as though “equal” rights have been taken away (i.e., marriage, tax breaks, etc.).
Skin color and other genetic traits can be traced through inheritance patterns and simple Mendelian genetics. Homosexuals are identified not by a trait or a gene, but rather by their actions. Without the action, they would be indistinguishable from all other people. It is only when they alter their behavior that they become a group that is recognized as being different. If we were to assume momentarily that homosexuality was genetic, then the most one could conclude is that those individuals were not morally responsible for being homosexual. However, that does not mean that they are not morally responsible for homosexual actions! Merely having the gene would not force one to carry out the behavior. For instance, if scientists were able to document that a “rape gene” existed, we certainly would not blame an individual for possessing this gene, but neither would we allow him to act upon that rape disposition. Neil Risch and his coworkers admitted:
There is little disagreement that male homosexual orientation is not a Mendelian trait. In fact, a priori, one would expect the role of a major gene in male homosexual orientation to be limited because of the strong selective pressures against such a gene. It is unlikely that a major gene underlying such a common trait could persist over time without an extraordinary counterbalancing mechanism (1993, 262:2064).
Evan S. Balaban, a neurobiologist at the Neurosciences Institute in San Diego, noted that
the search for the biological underpinnings of complex human traits has a sorry history of late. In recent years, researchers and the media have proclaimed the “discovery” of genes linked to alcoholism and mental illness as well as to homosexuality. None of the claims...has been confirmed (as quoted in Horgan, 1995).
Charles Mann agreed, stating: “Time and time again, scientists have claimed that particular genes or chromosomal regions are associated with behavioral traits, only to withdraw their findings when they were not replicated” (1994, 264:1687). It appears that the gay gene will be added to this category of unreplicated claims.
The real issue here is homosexual actions that society has deemed immoral and, in many instances, illegal. Since no study has firmly established an underlying genetic cause for homosexuality, arguments suggesting “equal rights” are both baseless and illogical.


Anyone who has tuned into prime-time television within the past few years has observed an increasing trend of shows featuring characters who are homosexual—and proud of it. It seems as though modern sitcoms require “token” homosexuals in order to be politically correct. The perception is that these individuals share the same apartment buildings, offices, clubs, etc., with heterosexual people, and that we need to realize just how prevalent homosexuality is. So, exactly what fraction of the population do homosexuals actually represent?
The famous Kinsey Institute report often is cited as evidence that 10% of the population is homosexual. In his book, Is It a Choice?: Answers to 300 of the Most Frequently Asked Questions About Gays and Lesbians, Eric Marcus used the Kinsey studies to demonstrate that one in ten people is homosexual (1993). In truth, Kinsey never reported figures that high. The Kinsey Report clearly stated that: “Only about 4 percent of the men [evaluated] were exclusively homosexual throughout their entire lives.... Only 2 or 3 percent of these women were exclusively homosexual their entire lives” (see Reinisch and Beasley, 1990, p. 140). However, there is good reason to believe that the real percentage is not even this high.
While no one has carried out a door-to-door census, we do have a fairly accurate estimate. Interestingly, these statistics came to light in an amicus curiae (“friend of the court”) brief filed with the U.S. Supreme Court on March 26, 2003, in the Lawrence vs. Texas case (commonly known as the Texas sodomy case). On page 16 of this legal brief, footnote 42 revealed that 31 homosexual and pro-homosexual groups admitted the following:
The most widely accepted study of sexual practices in the United States is the National Health and Social Life Survey (NHSLS). The NHSLS found that 2.8% of the male, and 1.4% of the female population identify themselves as gay, lesbian, or bisexual (Laumann, et al., 1994).
The study also found that only 0.9% of men and 0.4% of women reported having only same-sex partners since age 18—a figure that would represent a total of only 1.4 million Americans as homosexual (based on the last census report, showing roughly 292 million people living in America). The resulting accurate figures demonstrate that significantly less than one percent of the American population claims to be homosexual. The NHSLS results are similar to a survey conducted by the Minnesota Adolescent Health Survey (1986) of public school students. The survey showed that only 0.6% of the boys and 0.2% of the girls identified themselves as “mostly or 100% homosexual.”
The 2000 census sheds even more light on the subject. The overall statistics from the 2000 Census Bureau revealed:
  • The total population of the U.S. is 285,230,516.
  • The total number of households in the U.S. is 106,741,426.
  • The total number of unmarried same-sex households is 601,209.
Thus, out of a population of 106,741,426 households, homosexuals represent 0.42% of those households. That is less than one half of one percent!
But since most people are not mathematicians, we would like to make this point in a way that most individuals will be able to better comprehend. If we were to start a new television sitcom, and wanted to accurately portray homosexual ratios in society, we would need 199 heterosexual actors before we finally introduced one homosexual actor.
And yet modern television casts of three or four often include one or more homosexual actor(s). The statistics from the 2000 census are not figures grabbed from the air and placed on a political sign or Web site to promote a particular agenda. These were census data that were carefully collected from the entire United States population, contrary to the limited scope of studies designed to show a genetic cause for homosexuality.
