中性基因是一大类相对于显性基因而存在的遗传基因,平时它呈休眠状态,其携带的遗传信息不显现。但他能被一些内外因素激活显现,而当相关内外因素消失时,它又会恢复休眠状态。

利用群体遗传不平衡状态下的中性基因位点组合的遗传共适应特性,能揭示群体的起源进化和系统地位;通过对遗传共适应的认识,可提高经济性状标记的准确性。
With the genetic co-adaptability of loci combination under the condition of genetic disequilibrium, the genesis evolution and the system status of colony could be analyzed;
人类的大多数变异基因都是中性的,这意味着变异之所以被激发不是出于自然选择,而是由于产生了良性变异或染色体在复制时候发生了混乱。
Most variation in the human genome is neutral, meaning that it arose not by natural selection but by processes like harmless mutations and the random shuffling of the genome between generations.
中性蛋白酶- 1基因发出的强烈工作暗示使得蛋白质对神经肽产生反应。
A strong hint of how they work comes from the npr-1 gene, which makes a protein that responds to neuropeptides.
The genome starts piling on mutations that mean nothing; that's how they date the branches of the genome, by looking at the number of neutral mutations.
基因积累了许多无意义的突变,这就是他们如何鉴定基因分支的年代,看中性突变的数量就行了
