The principle that a subdivided population subject to overdominance viability selection in each habitat will manifest a unique, globally attractng polymorphic equilibrium is posited. This follows as a corollary to the stronger principle that, if haploid selection or submultiplicative diploid selection (definition: the geometric mean of the homozygote viabilities is less than or equal to the heterozygote viability) is operating in each habitat,there is a unique, globally attracting stable equilibrium that may be monomorphic or polymorphic. These principles are proven for a broad spectrum of migration patterns. In all such migration selection systems, multiple fixation states cannot be simultaneously stable under submultiplicative viability regimes. Contrasting examples where submultiplicative viabilities are not in force are given.
提出了一个原则，即在每个栖息地中受到超显性生存力选择的细分种群将表现出独特的、全球吸引的多态平衡。这是一个更强原则的推论，即如果在每个栖息地中存在单体选择或亚乘法二倍体选择（定义：纯合子生存力的几何平均值小于或等于杂合子生存力），则存在一个独特的、全球吸引的稳定平衡，该平衡可能是单态的或多态的。这些原则已经在广泛的迁移模式中得到证明。在所有这些迁移选择系统中，在亚乘法生存力的情况下，多个固定状态不可能同时稳定。给出了不适用亚乘法生存力的对比例子。
