Men in wigs and pumps are an overly extreme example of gay males and the same being said for women rocking male attire.

A recent scientific study has been completed that actually re-inforces the notion that homosexuality is a trait that some just so happen to be born with.
According to the report, the source may actually lie in epigenetics, or how the expression of genes is controlled by ?temporary switches? known as epi-marks.

Sex-specific ‘epi-marks’ are usually ‘erased’ from generation to generation, but when they don’t disappear, they can result in homosexuality.
Researchers have long believed that sexual orientation had some hereditary component and now they may actually have the proof to back up their theories.

In a study released Tuesday,?researchers from the National Institute for Mathematical and Biological Synthesis wrote that the answer of ‘why some people are gay’ may lie in epigenetics, or how the expression of genes is controlled by ?temporary switches? known as epi-marks.
As stated above, sex-specific epi-marks are usually ?erased? from generation to generation.?But when they do not disappear, they can be passed from father to daughter or mother to son, resulting in homosexuality in children.

?Transmission of sexually antagonistic epi-marks between generations is the most plausible evolutionary mechanism of the phenomenon of human homosexuality,? Sergey Gavrilets, the study?s co-author, said in a release.
Researchers have long believed that sexual orientation had some hereditary component.
However, scientists say that homosexuality, in terms of evolution, cannot be solely genetic, because the trait would eventually disappear given that homosexuals aren?t expected to reproduce.
Epi-marks, on the other hand, are thought to have an evolutionary advantage that keeps them within the population.

For instance, some epi-marks work to protect a female fetus from becoming too masculine if testosterone spikes in late pregnancy.
?These epi-marks protect fathers and mothers from excess or underexposure to testosterone ? when they carry over to opposite-sex offspring, it can cause the masculinization of females or the feminization of males,? William Rice, the study?s lead author,?told U.S. News & World Report.
Rice said that epi-marks are ?highly variable? and only those that are especially strong would potentially lead to homosexual children.
The evolutionary biologist said that while his theory still needs to be tested on parents and their children, it is the most plausible explanation so far.
?We’ve found a story that looks really good,” Rice said.
?This can be tested and proven within six months. It’s easy to test. If it’s a bad idea, we can throw it away in short order.”
I’ve always thought people were born that way, but what do I know… *shrug* ?They can offer all the explanations in the word and even provide solid proof, but I doubt that the debate will ever truly go away as to why some people are gay and some are not.
Which do YOU believe?
Is sexuality a “choice” made by an individual or is sexual preference already instilled in the genes prior to birth?
