As always, we would expect almost all interactions to be between male intruders and female natives (Neanderthals). In that case, some mixed male men with sufficient AMH traits may have made there way out and joined AMHs, will this would have likely been very difficult for mixed females. As a result, no uniparental markers were inherited into future generations.eurologisthttps://www.blogger.com/profile/03440019181278830033noreply@blogger.com
