Putting gene X into another species and expecting to see a behavior is unrealistic--a 'flight' gene from Drosophila, if it existed, is not going to make a mouse fly," Dickson explains, noting that only members of the same species might be expected to share the same set of "normal" behaviors.
"So you need to put gene X in a normal animal of the same species that doesn't normally do Y. This is really only possible with sex-specific behaviors" like courtship, he says.
"They courted other females, just as a normal male would, except that their sexual advances didn't get very far,"That's a direct quote from Dickson. It also mentioned how putting a fly's flight gene into a mouse can't make the mouse fly, which you quoted from your link. That has no bearing on the subject.
What does any of this have to do with human homosexuality?
If you know that then you might have the capacity to understand both studies cause their specimens to chemically have intersex disorder...ie. mosaic syndrome.
Which is cited where? Balakireva et al, 1998 thank you.
But it's not a bright shiny new study like yours so I guess it's bogus too.
