Abstract

A deterministic model allowing variation at a nuclear genetic locus in a population segregating two cytoplasmic types is formulated. Additive, multiplicative and symmetric viability matrices are analyzed for existence and stability of equilibria. The protectedness of polymorphisms in both nuclear genes and cytoplasmic types is also investigated in the general model. In no case is a complete polymorphism protected with this deterministic model. Results are discussed in light of the extensive variation in mtDNA that has recently been reported.

摘要

构建了一个确定性模型,该模型允许在一个群体中,在分离两种细胞质类型的核基因座处发生变异。分析了加性、乘性和对称生存力矩阵的平衡点的存在性和稳定性。在一般模型中还研究了核基因和细胞质类型中多态性的受保护情况。在任何情况下,这种确定性模型都不能保护完全多态性。根据最近报道的线粒体DNA的广泛变异对结果进行了讨论。
