The mitochondria and chloroplast have circular DNA which replicate independently during cell division. Now let us discuss the organisms given in the question. WebApr 11, 2024 · Therefore, because each cell’s physiology and spatiotemporal context determines gene expression, it is essential in analyses of phenotypic development to distinguish between cellular (nongenetic) inheritance and the two types of genetic inheritance (nuclear and mitochondrial) [6,73,74,75,76]. This distinction is most readily … Three general types of extranuclear inheritance exist. • Vegetative segregation results from random replication and partitioning of cytoplasmic organelles. It occurs with chloroplasts and mitochondria during mitotic cell divisions and results in daughter cells that contain a random sample of the parent cell's organelles. An example of vegetative segregation is with mitochondria of asexually replicating yeast cells. hans christian andersen little m
