Actually with regards to twins - you're wrong.

There are plenty of studies -- and right now I'm too sleepy to find them -- where genetically identical twins, but only one has a disease.

I went to high school with a set of twins like this -- one had muscular dystrophy, the other did NOT. BUT the one who didn't had the gene to "have" it. But for some reason it didn't switch "on." There are geneticists out there who study this to see what makes the genes flip on -- cause if they could figure that out, you never know what they could cure or prevent.

And I'm sleepy so that's a rather half baked explanation. . .I'll look for sources/studies later.

More proof that the twin studies are erroneous.

Can you point to the genetic marker for homosexuality please?
