According to the nature, characteristics can be divided into morphological, biochemical, physiological, psyhological, biochemical-physiological, psychophysical, ect. Among the morphological traits can vary: static-dynamic-morphological and morphological. The group dynamic morphological properties include those components whose phenotypic aspect of the individual is determined only when you run certain parts of the body or ergometrical or dynamometrical methods. The dynamical-morphological features include: bending the lateral edges of tongue, manner of clasping the hand, the way of crossing arms, extensibility of distal and proximal thumb joint. The aim of this study is population genetic analysis of thumb distal extensibility by age groups from 10 to 15 years of age both sexes in the example of Sapna population. Data for the study were obtained by direct observation (anthroposcopy) surveys of students and school children from third to eighth grade in elementary school 'Sapna' in Sapna. Data processing included complete morphological analysis of the dynamic properties of distal thumb joint hyper-extensibility and the frequency trend changes of different age groups. Based on the analysis frequency of alternative phenotypes extensibiity distal joint of the thumb in population of Sapna it is noted that allele gene frequency recessive distal flexibility (hitchhiker's inches) in the total sample is qdht=0,73. The frequency of recessive all elegenedistal flexibility in boys was qdht=0,74 and girls qdht=0,72, i.e. in boys is slightly higher. Trend of different age groups change of hyper-extensibility in distal thumb joint in the total sample is in a mild increase. .
