The Barag Mongolia Nationality Physical Anthropology And Population Genetics

Mongolia is the China main ethnic minorities. Barag Mongolian tribes belong to one of the many tribes. This paper describes the physical characteristics and to study the genetics and population characteristics Barag Mongolian. Researchers in 2013 8 reaches of Inner Mongolia Autonomous Region Hulun Buir City, New Barag Left Banner, select 400 Ming Baer Mongolian tiger at a local adult, male 196, female 204. Its body mass index in the 87 measurement and observation. City and Hulunbeier Hailar Hailar a Mongolian tiger Ming Baer in 286 students, including 95 boys,191 girls, were 25 population genetic phenotypic characteristics investigation. Use Excel2003, SPSS11.5, SPSS13.0 software and other survey data and statistical analysis.The results are as follows:(1) Barag Mongolian upper eyelid fold occurrence rate reached 58.0%, a lower rate of occurrence in Mongolia fold (40.0%), eye fissure height is more narrow, the emergence rate of 67.0%. Type eye fissure inclination, mostly above the outer corner of the eye angles eye type. Other indicators in the head and facial phenotype is more moderate type nasal root height, straight nasal dorsum, flat protruding zygomatic degrees horizontal base of the nose, the nose Medium height, lateral nose maximum diameter, medium and narrow width of the nose, ear lobes and middle circular type of skin upper lip height. Black hair color more yellow color more brown wink oriented. (2) Barag Mongolian whole head and face, body index value and the index values are closer to the North and type groups. Barag Mongolian men, women are the majority of the performance index for the length and width of the first short head type, head taller high index head type, head width and height index of wide head type, nasal index of nasal type, face shape index was broad surface type, height index is high type, tall, broad shoulders broad index type, height, chest circumference index Chest type Markov index trunk legs legs. Sex between different performance indicators are:male more performance for the long torso height sitting height index type, more performance for the female torso model. (3) Chest calm body circumference side, men's breath bust, waist circumference, abdominal circumference, hip circumference and women, exhale bust, waist circumference, abdominal circumference, hip circumference, arm circumference, forearm and upper arm circumference maximum and maximum circumference Age was positively correlated. (4) Barag Mongolian men of skinfold thickness indices no linear correlation with age; females age was positively related indicators biceps skinfold, crest skinfold before subscapularis skinfold and iliac. Women of the subcutaneous fat thickness indexes are up than men. (5) the average male body is 4.5-6.0-1.4, mesoderm, endoderm partial body belongs to the. Partial endoderm mesoderm body is the highest occurrence rate of body types. The average female body is 5.9-6.3-1.0 belonging endoderm-mesoderm balanced body, the highest occurrence rate of type mesodermal body partial endoderm. (6) minorities in China, Barag Mongolian taller, wider and longer head, a wide forehead, between the eyes wide apart. Compared with other ethnic groups, the physical characteristics of Barag Mongolian ethnic group and the North closer to having the type of North ethnic characteristics. (7) 9 Barag Mongolian head and face except for a genetic indicator of Mongoloid fold the remaining eight between the male and the differences were statistically significant; not all the indicators there are two wise correlations. (8) Barag Mongolian seven behavioral traits, the folding leg type occurrence rate a statistically significant difference between the sexes. In addition to the type of deduction hand, showed for the right type appear higher than the left type. Buckle Hand Type-folding leg type, hand-clasping Type-Li foot type, hand-clasping types-dominant eye type, handedness type-folding leg type, handedness Type-Li foot type, arm folding type-Lee foot type, folding leg type-the type of start and Lee foot type-the type of starting total of eight pairs of characters twenty-two correlation. (9) 5 tongue moving types in rates between gender difference was not statistically significant. In addition to rolling tongue and pointed tongue, the stack, tongue twisting, clover tongue rates appear low. Volume tongue-a sharp tongue, rolling tongue clover tongue rolling tongue-tongue twisting and folding tongue-a sharp tongue four pairs of characters twenty-two correlation. (10) and four indicators related to hand, foot, in addition to the type of thumb, but no statistically significant difference between the sexes, no correlation between any two.
