提供了一个均衡性别分配的一般方程，该方程模拟了儿子和女儿之间在后代生产成本、与控制基因型的遗传相关性以及交配机会和生殖资源的竞争数量方面的不对称。如果近亲交配是近亲繁殖的唯一来源，则对具有多种性别分配控制模式的二倍体和单倍体系统提供了有效的遗传证据。通过举例的方式，讨论了汉密尔顿（1967）模型的一些变化。
A general equation for equilibrium sex allocation is provided which models asymmetries between son and daughter in the costs of offspring production, the genetic relatedness to the controlling genotype and the amount of competition for mating opportunities and reproductive resources. A genetic proof is given which is valid for diploid and haplodiploid systems with a variety of modes of sex allocation control, provided sib mating is the only source of inbreeding. By way of example, some variations of Hamilton's (1967) model are discussed.
