5 True/False questions

  1. Causes of Dispersal at Proximal LevelBecause of the prevalence of polygyny, and associated tendency for males to disperse as they reach maturity, adult males are generally not related to other adults in the group. Males leave before they reach the age of maturity (sexually) and fathers leave before their daughters reach the age of maturity
