Nonadditive Genetic Variance: The Genetical Consequences of Population Structure

9307694晚安近年来，基因之间的相互作用对结构化种群进化的影响越来越受到关注。这是由于人们对结构化种群的普遍存在的认识，以及最近的几项研究表明，在细分的种群中，基因相互作用可以产生独特的进化结果%这项研究是一项理论研究，使用分析和数值方法来研究当存在基因交互时种群结构、遗传漂移和选择的影响。分析模式将检查遗传漂移对细分种群中遗传方差分布的影响。数值模拟将被用来探索选择在细分种群中的效果。此外，这些模拟将被用来检验基因相互作用在物种形成过程中的作用。

9307694 Goodnight In recent years the effect of interactions among genes on evolution in structured populations has received increased attention. This is due to an appreciation of the ubiquity of structured populations, along with several recent studies that demonstrate that in subdivided populations gene interactions can have unique evolutionary consequences%%%% This research is a theoretical study using analytical and numerical approaches to investigate the effects of population structure, genetic drift, and selection when there are gene interactions. The analytical modes will examine the effects of genetic drift on the distribution of genetic variance in subdivided populations. Numerical simulation will be used to explore the effects of selection in subdivided populations. In addition, the simulations will be used to examine the role of gene interaction in the process of speciation.***
