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.

该项目将启动有关孕产妇影响演变的研究。 数学模型将用于确定母体作用（例如哺乳动物中的泌乳）的强度如何发展。 我们将研究这些角色如何响应选择并开发方法来衡量其在自然种群中的选择和继承。 将用于实现这两个目标的具体方法是扩展主要研究者及其合作者最近引入的定量遗传模型，以及开发新的统计方法，以估算模型中出现的参数。 结果表格这项工作将指定孕产妇护理将起源和维护的条件，以及测试该理论产生的假设的经验方法。
