Comparison of phenotypic characteristics of hand and foot in adults of Hui and Han nationality in Southwestern Henan / 重庆医学

ABSTRACT

Objective To investigate the differences of hand and foot morphology and genetic phenotypic characteristics in adults of Hui and Han nationality in Southwestern Henan.Methods The indicators of height,weight,hand and foot were measured by the morphological measurements,the hand and foot genetic phenotype classification was observed and performed the statistical analysis.Results The hand width,foot length and foot width of the Hui adult men and women in Southwestern Henan were(8.27±0.55,23.10±1.20,9.34±0.83)cm and(7.41±0.44,20.50±1.23,8.79±0.69) cm,respectively,while which of the Han adult men and women were(8.56±0.09,24.57±1.33,9.47±0.70)cm and(7.74±0.36,22.46±1.21,8.91±0.85) cm,respectively.The total number of both hands fingerprint ridge line in Hui adult men and women were(135.06 ± 19.87) and (125.50 ±20.44)respectively,and which in Han adult men and women were (144.46 ±14.08) and (129.20 ± 20.34)respectively,the difference was statistically significant(P＜0.05).The tPD,atd angle and a-b crest line number among the Hui and Han nationalities were 16.07± 6.46,(44.61±8.66)°,34.04±5.47 and 16.53±6.27,(43.19±9.52)°,36.73±4.22 respectively.And the handedness,fingernail form,thumb type,footedness,right type ratio of foot and toe length of the Hui and Han nationalities were 90.01％,38.52％,85.59％,70.47％,56.92％ and 89.33％,45.26％,70.91％,96.98％,74.89％,respectively,the difference between the Hui and Han nationalities was statistically significant(P＜0.05).Conclusion The national differences and gender differences exist in the multiple indicators of hand and foot morphology,finger and palm prints,and genetic phenotype among the Hui and Han adults in Southwestern Henan.
