研究了一个双位点遗传模型，其中一个位点控制个体对兄弟姐妹利他行为的倾向，另一个位点控制雌性的交配习惯。它表明，在利他主义基因座的遗传变异往往是足够的，以诱导增加的频率的基因，导致女性产生所有的后代与一个单一的伴侣。这是因为导致利他主义的基因和影响雌性交配行为的基因之间存在非随机关联。这些结果为一夫一妻制的进化提供了一个新的解释，也为其他各种行为特征的进化提出了一个以前未被探索的机制。
A two-locus genetic model is studied in which one locus controls the tendency of individuals to act altruistically toward siblings and the other locus controls the mating habits of females. It is demonstrated that genetic variation at the altruism locus is often sufficient to induce an increase in the frequency of genes that cause females to produce all of their offspring with a single mate. This occurs because of nonrandom associations that develop between genes that cause altruism and those that affect female mating behavior. The results provide a new explanation for the evolution of monogamy, and they suggest a previously unexplored mechanism for the evolution of a variety of other behavioral traits as well.
