相对封闭区域内人指纹的遗传特性研究

The Research on Hereditary Property of Human Fingerprint in a Relative Enclosed Region

不同民族指纹纹型分布不同 ,同民族、不同地区人的指纹纹型分布也有差异。以一个较封闭群体为对象 ,研究指纹的遗传规律 ,发现斗型和尺箕型具有较强的显性特征。决定尺箕的基因可能也影响弓型纹型的表达 。

Different nations, the type of fingerprint is distributed differently; same nation and living in different area, the people have different fingerprint pattern distribution too. We selected a relative closed population to study the hereditary rules of fingerprint, and find that the whorl and the ulnar loop have strong trend into dominant characteristics. It is determined that the genes of ulnar loop may influence the expression of the genes of arch; and also the genes which determine the expression of whorl may influence the expression of double loop whorl.
