核外遗传又称细胞质遗传。指由核外(细胞质)的遗传 物质所控制的遗传。真核细胞生物在核外的细胞器,如线粒体、叶绿体中也存在少量的DNA,分别称为线粒体DNA (mtDNA)和叶绿体DNA (ctDNA),这些遗传单位统称 为核外遗传因子。
核外遗传(extranuclear inheritance):细胞核以外的遗传物质所决定的遗传现象。 雄性不育(male sterility):正常植株的变异体,其花粉败育,雌花发育正常,自花授粉...

结合物的细胞核基因是人类的,但是一小部分其它基因(位于细胞核外的称为线粒体的组织里面)来自兔子的遗传。
The nuclear genes of the result would be human, but a handful of other genes, which inhabit structures outside the nucleus, called mitochondria, would be inherited from the rabbit.
许多人认为,线粒体可能发挥更大的作用-包含细胞内的细胞核外的遗传物质。
Many believe mitochondria may play a bigger role - genetic material contained within the cell but outside the nucleus.
PHA刺激对淋巴细胞核内、外DBP的信号均有增高作用; DBP可能参与淋巴细胞的母细胞转化以及细胞间遗传信息的传递。
The results suggests that the PHA stimulation may affect both intranuclear and extranuclear DBP signals, and DBP may involve lymphoblastogenesis and inter-cellular genetic information transduction.
