In the course of long-term experiment on domestication of silver fox, it was necessary to determine the most important behavioral features, selection for which would give domestication effect. The mathematical method of principal components was used for the analysis of 20 fox behavior traits. The combination of the initial traits which reflected the structure of the integral trait, i.e. domesticated type of behavior, was determined. The practical use of this combination seems to more adequately estimate the level of domestication of a given animal, which is indispensable for subsequent effective selection.
在银狐长期驯化实验过程中，有必要确定最重要的行为特征，对其进行选择将产生驯化效果。采用主成分数学方法对20个狐狸行为特征进行分析。确定了反映整体特征结构即驯化行为类型的初始特征组合。这种组合的实际应用似乎能更充分地评估给定动物的驯化水平，这对于后续有效的选择是必不可少的。
