Eighty morphophysiological traits were studied in 55 males with a morphologically identical heterochromatin subtotal deletion of Y chromosome and in 55 males with a normal Y chromosome. No significant differences were found between these groups in mean values of most traits except some hematologic parameters. Using the pattern recognition algorithm a combination of 20 traits which differentiated the groups under comparison with the recognition errors 4.6% was extracted. The recognition system consisted the informative traits including electrocardiographic parameters (25% of the traits), some anthropological and hematologic traits and subjects' age. The results suggest that the Y chromosome heterochromatin appears to have a modifying effect on the phenotypic relationship between morphophysiological traits during human ontogenesis.
对55名Y染色体形态相同的异染色质部分缺失男性和55名Y染色体正常男性的80个形态生理特征进行了研究。除了一些血液学参数外，这些组在大多数特征的平均值上没有发现显著差异。使用模式识别算法，提取了20个特征的组合，该组合在区分比较组时识别错误率为4.6%。识别系统由信息特征组成，包括心电图参数（占特征的25%）、一些人类学和血液学特征以及受试者的年龄。结果表明，Y染色体异染色质在人类个体发育过程中似乎对形态生理特征之间的表型关系具有修饰作用。
