Homosexual genes and mating

According to
"Gay gene: A gene located on the X chromosome which was alleged to determine male homosexuality. The "gay gene" was dubbed homosexuality 1 (HMS1) and the male sexual orientation gene. It was thought to be in chromosome band Xq28. However, one would expect there to be strong selective pressures against a gene for male homosexual orientation. The original claim for the "gay gene" was made in 1993 by Dean H. Hamer and colleagues. There has been no independent confirmation of the existence of a "gay gene" and today there is considerable doubt about its existence." [My emphasis]
A good friend of mine sent me the below analysis to demonstrate that a gay gene is doomed to extinction after seven generations. Please read it and comment if you wish:
Here is a common sense look at the homosexual gene controversy. As a scientist and graduate research chemist (published and hold 2 patents), I studied Gregor Mendel in HS, who is considered by Wikipedia to be the father of modern genetics. Mendel studed pea plants to determine traits passed on through dominant and recessive genes. In each case he mated the male and female parts of the plants to accomplish his work. Homosexual organisms do not mate by definition and bisexual organisms like mammals must mate to pass ANY trait from one generation to the next. Whether dominate or recessive the theoretical existence of a homosexual gene or any other trait cannot be passed from one generation to another in bisexual organisms without mating. Assuming a dominate gene present at 100% in the first generation, the dilution factor after just 7 generations yields the claimed percentage of homosexuals present in U.S. society. At 11 generations, there is just 1/10th of 1% of the trait present without any mating of the organisms. After hundreds of generations, the dilution factor precludes any realistic possibility.  
GenerationTrait, %
Starting with Gregor Mendel and thousands of biologists since then it has been demonstrated conclusively that traits cannot be passed in bisexual organisms without mating. The theory of homosexual traits or tendencies being passed across multiple human generations is scientifically bogus. Like many theories put forth without scientific merit there is an overriding political and/or sociological agenda, which is being served but science should not be drawn into such wrong-headed thinking.
According to Brad Harrub, Ph.D. and Bert Thompson, Ph.D. and Dave Miller, Ph.D.
"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'.
