Significant heterogeneity in the distribution of within pair variances of serum total cholesterol, HDL cholesterol, non HDL cholesterol and triglyceride levels has been found in one or both of two samples of MZ twins. We have found some support for the observation of Magnus et al. (1981) that M- pairs have greater environmental variability in cholesterol levels than M+ pairs and weaker evidence that Jka+ pairs are more variable than Jka- pairs. However, these effects appear to be more striking on triglyceride levels. The low power of the variance ratio test is advanced as a possible reason for the inconsistencies in these findings.
在同卵双胞胎的两个样本中的一个或两个中，已发现血清总胆固醇、高密度脂蛋白胆固醇、非高密度脂蛋白胆固醇和甘油三酯水平的配对内方差分布存在显著异质性。我们发现有一些证据支持Magnus等人（1981年）的观察结果，即M-对双胞胎在胆固醇水平上的环境变异性比M+对双胞胎更大，而关于Jka+对双胞胎比Jka-对双胞胎更具变异性的证据则较弱。然而，这些影响在甘油三酯水平上似乎更为显著。方差比检验的低效能被认为是这些研究结果不一致的一个可能原因。
