在一组free-rangingMacacamulatta的生殖活动的数据进行了分析，试图评估男性的优势择偶时，男性生殖性能的权重与排卵和受孕的可能性。在本研究中，排卵被假定发生在“吸引力下降”之前的四天内，也就是月经周期中假定与黄体期开始一致的时刻，雄虫的优势等级与其交配频率和交配时间呈正相关在排卵期。然而，与Altmann（1962）的“访问模型的优先级”的预测版本的数据的比较表明，男性排名并不能解释所有的男性生殖活动的变化。由于男性的克制，男性的选择性和女性的选择的偏差进行了讨论的范围内的一些不对称的竞争能力的男性（而不是优势），并在从伴侣的回报。女性的选择似乎提供了一种回报的不对称性，这是被拒绝的追求者无法轻易克服的。这表明，所观察到的男性等级和生殖性能之间的正相关性，从男性的竞争interactionacts concurrentlywith男性的能力，影响女性的选择（例如，通过在财团的低级别的男性干扰）。
Data on reproductive activity in one group of free-rangingMacaca mulattawere analysed in an attempt to assess the explanatory power of male dominance for mate selection when male reproductive performance is weighted in relation to the likelihood of ovulation and conception. In the present study, ovulation was assumed to have taken place during the four-day period preceding the ‘attractiveness breakdown’, that is, the moment in the menstrual cycle presumed to coincide with the onset of the luteal phase, the diagnostic criterion being the termination of consorting activity.Positive correlations were found between the dominance rank of males and both their copulatory frequencies and the time which they spent consorting during ovulatory periods. However, the comparison of the data with the predictions of a version of Altmann's (1962) ‘priority of access model’ shows that male rank does not explain all the variance in male reproductive activity. Deviations due to male abstention, male selectivity and female choice are discussed in the context of a number of asymmetries in the competitive ability of males (other than dominance) and in payoff from consorting. Female choice appeared to provide a payoff asymmetry which could not be easily overcome by the rebuffed suitor. This suggests that the observed positive correlation between male rank and reproductive performance resulted from male-male competitive interactionsacting concurrentlywith the capacity of males to influence female choice (e.g. through interferences in the consortships of lower-ranking males).
