I formulate and study a series of simple one-locus two-allele models for maternal (parental) selection. I show that maternal (parental) selection can result in simultaneous stability of equilibria of different types. Thus, in the presence of maternal (parental) selection the outcome of population evolution can significantly depend on initial conditions. With maternal selection, genetic variability can be maintained in the population even if none of the offspring of heterozygous mothers survive. I demonstrate that interactions of maternal and paternal selection can result in stable oscillations of genotype frequencies. A necessary condition for cycling is strong selection.
我构建并研究了一系列用于母系（亲代）选择的简单单基因座双等位基因模型。我表明母系（亲代）选择可导致不同类型平衡的同时稳定性。因此，在存在母系（亲代）选择的情况下，种群进化的结果可能会显著取决于初始条件。有了母系选择，即使杂合子母亲的后代无一存活，种群中的遗传变异性也可得以维持。我证明母系和父系选择的相互作用可导致基因型频率的稳定振荡。循环的一个必要条件是强选择。
