A study of genetic traces from interbreeding between Homo sapiens and Neanderthals suggests that matings typically involved female modern humans and male Neanderthals, though researchers debate whether this reflects mating preferences, population dynamics, or other genetic factors. The analysis found that human X chromosomes contain far less Neanderthal DNA than other chromosomes, a pattern some geneticists say is inconclusive and requires additional evidence to confirm.
