In most sexual organisms, including isogamous, anisogamous and oogamous organisms, uniparental transmission is a striking and universal characteristic of the transmission of organelle (plastid and mitochondrial) genomes (DNA). Using genetic, biochemical and molecular biological techniques, mechanisms of uniparental (maternal and parental) and biparental transmission of organelle genomes have been studied and reviewed. Although to date there has been no cytological review of the transmission of organelle genomes, cytology offers advantages in terms of direct evidence and can enhance global studies of the transmission of organelle genomes. In this review, I focus on the cytological mechanism of uniparental inheritance by "active digestion of male or female organelle nuclei (nucleoids, DNA)" which is universal among isogamous, anisogamous, and oogamous organisms. The global existence of uniparental transmission since the evolution of sexual eukaryotes may imply that the cell nuclear genome continues to inhibit quantitative evolution of organelles by organelle recombination.
在大多数有性生物中，包括同配、异配和卵配生物，亲代遗传是细胞器（质体和线粒体）基因组（DNA）传递的一个显著和普遍的特征。利用遗传、生化和分子生物学技术，已经研究和综述了细胞器基因组的单亲（母系和父系）和双亲传递的机制。尽管迄今为止还没有细胞器基因组传递的细胞学综述，但细胞学在提供直接证据方面具有优势，并可以增强细胞器基因组传递的全球研究。在这篇综述中，我重点关注了“主动消化雄性或雌性细胞器核（核体、DNA）”的单亲遗传的细胞学机制，这种机制在同配、异配和卵配生物中普遍存在。自从有性真核生物进化以来，全球范围内存在的单亲遗传可能意味着，细胞核基因组通过细胞器重组继续抑制细胞器的定量进化。
