Abstract

A general linear model is described here for cultural and biological inheritance of lipids and lipoproteins. This model involves 10 parameters to be estimated from a total of 17 correlations, leaving ample degrees of freedom to test the goodness of fit. The model fits very well to each of the five lipid and lipoprotein variables analyzed here from a Lipid Research Clinic family data set. Both genetic and cultural inheritance are significant for each trait with the single exception that triglyceride levels fail to support genetic inheritance. Under the most parsimonious hypothesis, the genetic heritability (h2) ranges from .194 +/- .092 for triglyceride to .624 +/- .093 for low-density lipoprotein-cholesterol. Cultural heritability ranges from .070 +/- .030 for total cholesterol to .149 +/- .034 for triglyceride.

摘要

本文描述了一个用于脂质和脂蛋白的文化与生物遗传的一般线性模型。该模型涉及10个需从总共17个相关性中估计的参数,从而为检验拟合优度留出了充足的自由度。该模型与脂质研究诊所家庭数据集里分析的五个脂质和脂蛋白变量中的每一个都拟合得非常好。除甘油三酯水平不支持遗传继承这一唯一例外,遗传和文化继承对每个性状都很显著。在最简约的假设下,遗传遗传力(h2)范围从甘油三酯的0.194±0.092到低密度脂蛋白胆固醇的0.624±0.093。文化遗传力范围从总胆固醇的0.070±0.030到甘油三酯的0.149±0.034。
