Mum's the Word?

A study showing that dominant Bonobo mothers give their sons a 'leg up' by facilitating their matings (perhaps it should be called a 'leg over?) makes good evolutionary sense (https://www.theguardian.com/science/2019/may/20/pushy-bonobo-mothers-help-sons-find-sexual-partners-scientists-find). The mothers reportedly usher their boys into locations where fertile females are found and even attack other males who attempt to join in the activity. She, of course, shares 50% of her genes with her son and every fertilisation passes on 25% of these genes.
