Aside from skin tone or color, probably nothing
Not quite they would still look different from a European if they had light skin, slightly different facial proportions, they would tend to be taller with longer limbs and head hair is a little more frizzy I suppose. I'm not sure if they really have a larger dong on average if that's a myth. There was a book I read years ago that covered all of this in some detail including charts with the measurements of the physical proportions along with averages of IQ and that kind of thing. It does sound a bit un-PC but it was a reasonable scientific book.
They would be able to do if they are the exact same species. I think we even managed to breed with the neanderthals so they would have been more a sub-species.plus they can interbreed.
