1. BORN OR BRED?
Science Does Not Support the Claim That Homosexuality Is Genetic By Robert Knight
The media splashed the study on front pages and TV and radio broadcasts from coast to coast,despite the fact that LeVay himself cautioned:“It’s important to stress what I didn’t find. I did not prove that homosexuality is genetic, or find a genetic cause for being gay. I didn’t show that gay men are born that way, the most common mistake people make in interpreting my work. Nor did I locate a gay center in the brain. …Since I looked at adult brains, we don’t know if the differences I found were there at birth, or if they appeared later.” ......

Even if science were to one day prove an incontrovertible genetic basis for homosexuality, those who disagree might then simply label homosexuality a genetic disease or disorder. ......

3.What Causes Homosexuality?

This is the first and perhaps the most basic question about homosexuality. In order to understand the phenomenon of same-sex sexual relations, we must first explore what the research shows about the origins of such attractions.
There are two main theories as to what causes homosexual attractions. One is that a homosexual orientation is essentially dictated by genetic and or biological factors—put simply, that people are “born gay.” The other theory is that homosexual attractions develop as primarily as a result of psychological and environmental influences and early experiences. In the public square, the latter theory has appeared to be in decline and the former gaining favor in recent decades. But what does the research show? Let’s look at these two theories in turn. ......

and the “Gay Gene”

It’s important to stress what I didn’t find. I did not prove that homosexuality is genetic, or find a genetic cause for being gay. I didn’t show that gay men are born that way, the most common mistake people make in interpreting my work. Nor did I locate a gay center in the brain (as quoted in Byrd, et al., 2001, emp. added).

5.The “discovery” of the “gay gene”

Summary
The scientific community realises that “our genes do not make us do it”. Hamer has always believed that. To give him the last word: “There will never be a test that will say for certain whether a child will be gay. We know that for certain.”16 This means as clearly as anyone could state, that no-one is born gay.
Proponents of the view that homosexuality has psychological
and sociological explanations have no difficulty with the possibility of genetic linkages to homosexuality.
They would argue that any genetic link to a physical characteristic that might heighten a person’s sense of gender nonconformity (the strongest known predictor of Chapter Nine: The “discovery” of the “gay gene” 173 later homosexuality), could be held to be a contributing factor to later homosexuality. In a boy these might be, e.g. genes related to slightness of build or poor physical co-ordination (making a boy poor at sports). In a girl they might be factors like atypical physical strength, shape, height, or weight. Links? Yes, but weak and indirect.
