本文对汉族446个家庭,共1788名成员的指端箕形纹的遗传特点进行了研究。结果发现,指端箕形纹也受着遗传的控制,其遗传方式不是由外显充分的单基因常染色体显性或隐性遗传。根据Falconer第一公式计算其遗传度为76.38％,支持指端箕形纹亦属多基因遗传的观点。
In this paper, the genetic characteristics of fingerprinted lines of 448 families and 1788 members of the Han nationality were studied. The results showed that fingerprinting Kewen pattern is also subject to genetic control, and its genetic mode is not significantly overt monosomy autosomal dominant or recessive inheritance. According to Falconer’s first formula, the heritability was calculated to be 76.38%, supporting the view that polygamy also means polygenic inheritance.
