The ratio of men to women in a given ecology can have profound influences on a range of interpersonal processes, from marriage and divorce rates to risk-taking and violent crime. Here, we organize such processes into two categories - intersexual choice and intrasexual competition - representing focal effects of imbalanced sex ratios.
在特定生态系统中，男性与女性的比例会对一系列人际过程产生深远影响，包括结婚率和离婚率、冒险行为和暴力犯罪。在这里，我们将这些过程分为两类——两性选择和同性竞争——代表了性别比例失衡的焦点效应。
