摘要
作者认为胎儿手指皮肤表皮和表皮初级嵴形成受两种不同基因控制,且控制表皮和表皮初级嵴发育的两种基因,由于突变可以相互转化。作者给出描述基因控制过程的微分方程。根据微分方程,阐述了皮纹模式形成的基因作用机制。
In this paper we assume that there are two different types of the genes action in the development and differentiation of the epidermis and epidermais prim- ary ridges and they can turn into each other.The evolution equations of gene were given.The mechanism of the gene action in the development and the differentiation of the epidermis and epidermais primary ridges was explained acco- rding to the numerical solution of the evolution equation of the gene.
