在本文中，我们开发了一个通用的方法来确定进化平衡性别比例和检查进化稳定性，连续稳定性和侵入性的精确遗传模型与显性或非显性。然后将该方法应用于三种结构种群模型：第一种是汉密尔顿的LMC模型，只考虑了一部分β雌性后代与同一群体中出生的雄性后代交配，而一部分1 -β雌性后代与整个种群中随机选择的雄性后代交配;在第三个模型中，雄性和雌性后代的部分分散发生在交配之前。在第一个模型中，人口调节的影响进行了研究，而在其他模型中，两种扩散被认为是：比例和均匀。(C)北京大学出版社.
In this paper, we develop a general method to determine evolutionary equilibrium sex ratios and to check evolutionary stability, continuous stability and invadability in exact genetic models with or without dominance. This method is then applied to three kinds of models for structured populations: the first one concerns Hamilton's LMC model except that only a fraction beta of female offspring mate with male offspring born in the same colonies, while a fraction 1 - beta mate with male offspring chosen at random within the whole population; in the second model, it is assumed that partial dispersal of inseminated females occurs after mating; in the third model, partial dispersal of male and female offspring occurs before mating. In the first model, the effect of population regulation is studied while, in the other models, two kinds of dispersal are considered: proportional and uniform. (C) 2000 Academic Press.
