The genetical and environmental structure of covariation between finger ridge counts in twin and sibling data has been analysed using the method of Martin and Eaves (1977) adapted from Jöreskog. 2. The model for environmental covariance contains a single factor loading on all ten digits but most environmental variance is specific to each finger. 3. For additive genetic variance there is one common factor loading on all digits. There are also five other independent factors, one for each digit. The thumb factor loads only on the two thumbs but the four fingers load on the finger in question and on the adjacent fingers. 4. A single common factor for non-additive genetic variance produces a considerable improvement in the model. 5. The pattern of genetic effects differs between left and right hands. 6. Although the same model is appropriate for males and females, different parameters estimates are required. 7. The fit of models is sensitive to the scale of measurement.

利用改编自约雷斯科格的马丁和伊夫斯（1977年）的方法，对双胞胎和兄弟姐妹数据中手指嵴纹计数之间协变的遗传和环境结构进行了分析。2. 环境协方差模型在所有十个手指上包含一个单一因子负荷，但大多数环境方差是每个手指特有的。3. 对于加性遗传方差，所有手指上有一个共同因子负荷。还有其他五个独立因子，每个手指一个。拇指因子仅加载在两个拇指上，但四个手指加载在所讨论的手指和相邻手指上。4. 非加性遗传方差的单个共同因子在模型中产生了相当大的改进。5. 左右手的遗传效应模式不同。6. 虽然相同的模型适用于男性和女性，但需要不同的参数估计。7. 模型的拟合对测量尺度敏感。
