n.直系同源基因

C. elegans REC-8 is the likely worm ortholog of yeast Rec8. 线虫REC-8已被证明是参与减数分裂的重要姐妹染色单体粘连蛋白。

The murine ortholog of GPRA was up-regulated in a mouse model of ovalbumin-induced inflammation. 小鼠同源GPRA在卵白蛋白诱发炎症的小鼠模型中出现上调。

OsPDCD5, an ortholog to mammalian programmed cell death 5, was previously cloned from rice, and its overexpression can induce PCD in transgenic rice. 程序性细胞死亡(PCD)是生物体内高度协调的生理过程，在植物发育、分化和压力诱导下都发挥着重要作用。

Among these genes is GINS3, the human ortholog of which is a major locus in 2 concurrent human genome-wide association studies of QT interval. 在这些基因中，QT间期的两个同时进行的人类全基因组相关性的研究证明GINS3在人类基因中存在一个主要基因位点。

Data mining and comprehensive analysis by sequence against database similarity searching, ortholog structure comparison, expression profile analysis and gene "neighbor" listing were performed. 方法 :利用数据库相似性搜索、同源物结构比较、表达谱分析和查询基因“邻居”等技术进行数据发掘和数据综合分析。

For example, the coding sequence of a human protein-coding gene is typically about 80% identical to its mouse ortholog, while their genomes as a whole are much more widely diverged. 人类蛋白质编码因子编码排序与其老鼠ortholog相比典型地具有大约80%25的同一性，虽然它们的基因组整体上有更多分*。
