This project will initiate studies on the evolution of maternal effects. Mathematical models will be used to determine how the strengths of maternal effects (for example, lactation in mammals) evolve. We will study how these characters respond to selection and develop methods to measure their selection and inheritance in natural populations. Specific approaches that will be used to meet these two objectives will be the extention of a quantitative-genetic model recently introduced by the principal investigator and his collaborators, and the development of new statistical methods for estimating the parameters that appear in the models. Results form this work will specify the conditions under which maternal care will originate and be maintained, and empirical methods for testing the hypotheses generated by the theory.

该项目将启动关于母体效应演变的研究。 数学模型将用于确定母体影响（例如哺乳动物的哺乳）的强度如何演变。 我们将研究这些性状如何对选择做出反应，并开发测量它们在自然群体中的选择和遗传的方法。 用于实现这两个目标的具体方法将是主要研究者及其合作者最近引入的定量遗传模型的扩展，以及用于估计模型中出现的参数的新统计方法的开发。 这项工作的结果将具体说明孕产妇护理产生和维持的条件，以及检验该理论产生的假设的实证方法。
