Abstract

Segregation analysis is a basic tool in human genetics. It is a statistical method to determine if a trait, continuous or binary, has a transmission pattern in pedigrees that is consistent with Mendelian segregation. Major locus segregation is combined together with multifactorial/polygenic inheritance in the unified model. Segregation analysis as a procedure to identify the presence of segregation at a major Mendelian locus, with/without multifactorial inheritance, is introduced in this chapter. It is illustrated with the program SEGREG in the Statistical Analysis for Genetic Epidemiology (S.A.G.E.) package, which can use either regressive models or the finite polygenic mixed model to incorporate the multifactorial/polygenic component.

摘要

分离分析是人类遗传学中的一种基本工具。它是一种统计方法，用于确定一种性状（连续性状或二元性状）在系谱中的传递模式是否符合孟德尔分离定律。在统一模型中，主要基因座分离与多因素/多基因遗传结合在一起。本章介绍了作为一种程序的分离分析，用于识别主要孟德尔基因座上是否存在分离现象，无论有无多因素遗传。文中以遗传流行病学统计分析（S.A.G.E.）软件包中的SEGREG程序为例进行说明，该程序可以使用回归模型或有限多基因混合模型来纳入多因素/多基因成分。
