We don't know much about the epigenetic differences between human populations. There has yet to be an “epi”Genome project. But there really isn't that much difference between humans. If there was an appreciable difference in epigenetic sexual differences then reciprocal crosses between populations would be different (i.e. a child of a male Amerindian and a female European would be different than the child of a male European and a female Amerindian). I don't believe there is any evidence that this is the case, and neither is there really a reason to suspect it.

Thank you for the reply.

“If there was an appreciable difference in epigenetic sexual differences then reciprocal crosses between populations would be different”

Is this opinion the result of research? The first part of your answer suggests not. I’ll admit that I would expect there to be differences.
