蒙古国喀尔喀部蒙古族4项群体指趾遗传学特征研究

在内蒙古民族大学调查了160例(男66例,女94例)来自蒙古国的喀尔喀蒙古族留学生的拇指类型、环食指长、指甲形状、足趾长4项群体指趾遗传学特征。研究结果:1)直型拇指率为44.38%,环指长率78.13%,指甲形状长型率58.75%、方型率6.88%、扁型率34.38%,足趾类型拇趾长率35.00%;2)指甲形状出现率性别间差异具统计学意义,两两特征间均未表现出明显相关关系;3)与我国10个蒙古族族群相比,多数差异具有统计学意义。

A Study of Four Types of Genetic Characters of the Khalkha Mongolian People of Mongolia

Four genetic characteristics of thumb type, palmar digital formula, fingernail type and plantar digital formula of 160 Mongolian college students (66 males, 94 females) from Kamika, Mongolia were measured. The results are as follows, 1) Frequencies of the straight thumb, longer and ring finger, long-shaped fingernail, squat-shaped, big toes and flat-shaped are 44.38%, 78.13%, 58.75%, 6.88%, 34.38% and 35.00%, respectively. 2) There are significant sexual differences in the frequency of the palmar digital formula, however there is no significant difference between each of two characteristics. 3) Compared with Mongolian groups from China, it is concluded that the Khalkha Mongolian has significant differences in four characteristics of thumb type, palmar digital formula, fingernail type and plantar digital formula.
