In this case their sampling was 47 sets of twins. In 37 sets on was homosexual. In the other 10 sets, both were gay. This is certainly not a representative sampling of the general public.

This will fall into obscurity in short order. When the try a sampling of the general population, it will not prove their thesis. This is bad science, if it is science at all.

patterns of molecules which attach to DNA to switch genes on and off were associated with homosexuality

I agree that this is bad science. It is just as likely that homosexual behavior caused these effects mentioned above. Imagine, for example, a male receiving within his blood or lymph system the uniquely male component called sperm. His body defenses would fight this invader and produce defenses against it. What would the molecular structure of those defense or their by-products be? Where would they locate? etc.
