本文对600名蒙古族正常青少年进行10项皮纹学指标的检查和统计学处理。对各项皮纹指标进行了性别之间,手别之间,以及与汉族青少年的检查结果进行比较分析。发现蒙古族正常青少年的皮纹有如下特点: 指纹中W纹出现率占首位,明显地高于汉族人,A纹出现率低于汉族。TRC存在性别间的差异,女性低于男性。C三叉点缺失频率高于汉族人,双手C三叉点缺失占3.33％。大鱼际区皮纹型出现率明显低于汉族人,而小鱼际区皮纹型的出现率高于汉族。掌atd角女性大于男性,>46度者占8.75％,明显多于汉族。TDR值存在男、女性别上的差异,女性大于男性。通贯手频率为2.5％,高于汉族,双侧通贯手频率为0.25％。为了弄清我国各民族皮纹的分布特点,丰富和充实我国人类遗传学和医学遗传学知识。我们在进行汉族青少年皮纹学调查后,于1980年,对蒙古族青少年10个项目的皮纹学正常值进行了检查和统计学处理,现将调查结果报告如下:
In this paper, 600 samples of Mongolian normal teens were examined and statistically analyzed. Conducted a comparative analysis of the various dermatoglyphs between sex, between the hand and other, and with the examination results of the Han adolescents. Found that Mongolian normal teens have the following characteristics: the appearance of W fingerprint in the first place, significantly higher than the Han people, A pattern lower than the Han rate. There are gender differences in TRC and women are lower than men. C trigeminal point deletion frequency is higher than the Han people, hands C trigeminal point loss accounted for 3.33%. The occurrence rate of dermatoglyphic pattern in the big intertidal zone was significantly lower than that of the Han nationality, while that of the dermatoglioid zone in the minor zone was higher than that of the Han nationality. Palm atd angle female than male,> 46 degrees accounted for 8.75%, significantly more than Han. TDR values exist differences between men and women, women than men. Pass frequency of 2.5%, higher than the Han, bilateral pass frequency of 0.25%. In order to clarify the distribution characteristics of various ethnic lines in our country, enrich and enrich our knowledge of human genetics and medical genetics. After conducting a survey on the dermatoglyphics of the Han youth, we conducted a survey and statistical treatment of the normal dermatoglyphics of 10 Mongolian adolescents in 1980, and the results of the survey are reported as follows:
