AT the level of the egg and sperm ~

It is rather unlikely that anyone would seek such a treatment for their unborn child, and it would be unknown if epigenetic intervention before puberty (when sexual attraction is usually determined) would be effective. But it might be effective as a screen, something people could test for.

But as they say with most prenatal screening, don't do it unless you are willing to act (abort) on the information.

If there were an effective screen for these epigenetic markers and a couple could tell if the child was likely to be homosexual - would be find social conservatives suddenly pro-abort, and homosexuals suddenly anti-abortion?
