模型提出了进化在一个单一的基因座影响利他行为，其中基因型适合达尔文和频率（但不是密度）依赖。适合度是由依赖于利他行为的接受和捐赠的因素以乘法或加法的方式组成的。因子由描述亲属基因型的条件概率矩阵确定。由于选择发生，这些概率是基因型频率。风险之间的关系，以帮助者和受益者，使利他主义的发展取决于帮助者和帮助之间的亲属关系系数，提出的特定的健身功能和利他主义的主导程度。W.D.汉密尔顿（1964）只适用于加法情形。讨论了第二类与关系无关的社会合作模型及其演化动力学。
Models are proposed for evolution at a single locus affecting altruistic behavior in which genotypic fitnesses are Darwinian and frequency (but not density) dependent. The fitnesses are composed, either in a multiplicative or an additive way, of factors which depend on the receipt and donation of altuistic behavior. Factors are determined from matrices of conditional probabilities which describe the genotypes of relatives. Since selection occurs, these probabilities are in terms of genotype frequencies. The relationship between the risk to helper and benefit to recipient which allows altruism to evolve is shown to depend on the kinship coefficient between helper and helped, the particular fitness function proposed and the degree of dominance of the altruism. The commonly accepted criteria of W.D. Hamilton (1964) apply only in the additive case. A 2nd class of models of social cooperation independent of relationship and its evolutionary dynamics are discussed.
