质体和线粒体含有共价闭合的环状DNA分子群体，其复制和遗传独立于核DNA。叶绿体DNA（cpDNA）和线粒体DNA（mtDNA）向子代的传递由受精时的母本和父本输入以及受精卵的消除机制决定。此外，由于每个细胞有许多细胞器，每个细胞器有许多DNA分子，遗传模式也受到细胞分裂时营养分选和生殖细胞谱系中分子复制速率差异的影响。十年前，对细胞器传递的研究仅限于少数几种有遗传标记的生物，并且有可能假设细胞器遗传学的“定律”1
PLASTIDS and mitochondria contain populations of covalently closed circular DNA molecules that are replicated and inherited independently of nuclear DNA. Transmission of chloroplast DNA (cpDNA) and mitochondrial DNA (mtDNA) to progeny is determined by maternal and paternal inputs at fertilization and by mechanisms of elimination from the zygote. In addition, because there are many organelles per cell and DNA molecules per organelle, inheritance patterns are also influenced by vegetative sorting at cell division and by differences in replication rates among molecules in germ-celllineages. A decade ago, research on organelle transmission was limited to the few organisms for which genetic markers were available, and it was possible to postulate'laws' of organelle genetics1
