原因在于，当一个理想版本基因“扫描”一个人群，变异便开始在DNA中逐渐累积，这会将基因的统一性——基因扫描的证据——加以破坏。
The reason is that after a favored version of a gene has swept through the population, mutations start building up in its DNA, eroding the uniformity that is evidence of a sweep.
当一个基因变异足够累积，会变成“假基因”，这意味着它无法再为有效感受器编码。

When regulation fails, genome aberrations accumulate, including repeated sequences of DNA or een entire extra chromosomes.
分析结果显示，细胞在累积错误折叠蛋白的部位产生了一些微小rnas，是一些能够调控基因表达的小分子。
Analyses indicate that part of the cell response to the accumulation of misfolded proteins is the production of several micro-RNAs, small molecules that regulate gene expression.
而且，还不知道累积持续DNA损伤的关键基因区域。
Moreover, critical genomic regions engaged in persistent DNA damage accumulation are unknown.
同时，AGA适应度函数定义为BP网络的累积预测误差的标准偏差和基因的终止条件之一。
Meanwhile, AGA fitness function is defined as the standard deviation of BP network's accumulation forecast errors and also one of genetic termination criteria.
研究结果表明，控制基因的细微变化可以导致有机体的细微变化，经过不断的累积，就可能产生新的物种。
These results show that slight changes in the control regions of genes lead to slight changes in the organism, and accumulation of such small differences may result in the creation of a new species.
肿瘤是各种原因导致多基因突变累积和相互作用形成的基因网络调控的结果，通过干预致瘤因子可能达到治疗肿瘤或改变肿瘤特性的目的。
Tumors are the results of accumulation of multiple gene mutations and their interactions. So by the intervention on tumorigenic factors, we may cure tumors or change their properties.
他说，加拿大的研究人员早就预期会有抗药基因的累积，但由于除草剂的种类远多过抗药基因，因此控制这些植物的生长，不会比单一基因改造的品种更困难。
Canadian researchers expected resistance genes to accumulate, he says, and because there are more herbicides than resistance genes, the plants are just as easy to control as singly modified varieties.
人类基因的常见变异会将较小影响累积，而对表型影响较大。
Common variants in the human genome may make a small impact which cumulatively may have a large impact on phenotype.
从分子生物学角度讲，大肠癌的发生是一个多基因、多步骤的累积过程。
