研究了一类生存模型，它推广了标准可加模型中的两两可加性和上位性相互作用。分析了相应的两轨迹模型中平衡态的存在性和稳定性条件。利用正则摄动方法，研究了选择弱于重组和选择强于重组的情形。导出的结果是用来作出结论的选择强度和重组率之间的关系的人口特征的依赖。
A class of viability models that generalize the standard additive model for the case of pairwise additive by additive epistatic interactions is considered. Conditions for existence and stability of steady states in the corresponding two-locus model are analyzed. Using regular perturbation techniques, the case when selection is weaker than recombination and the case when selection is stronger than recombination are investigated. The results derived are used to make conclusions on the dependence of population characteristics on the relation between the strength of selection and the recombination rate.
