>Isn’t there a claim that known evidence shows it was mostly Neanderthal females + human males that resulted in offspring and not much of the other combo? There may well be such a claim, although I hadn't heard it before. However, IIUC, there isn't really evidence for Neanderthal genes in mitochondrial DNA[0] which is passed, unchanged, through the maternal line. It's certainly possible that at some point, all female descendants of female Neanderthal ancestors somehow didn't reproduce. Perhaps there was some incompatibility between human and Neanderthal X chromosomes? Or perhaps it was that Neanderthal males procreated with human females at a much higher rate? We'll likely never know for sure.
