Introduction: Cell Division (Principles): Mitosis and Meiosis The cell division process forms the basis of all life that exists on the Earth, whether it is a prokaryotic or eukaryotic life form. Each daughter cell inherits 2 sister chromatids (the replicated chromosome), but only 1 of the homologous pair (either the paternal or maternal chromosome). During M phase, the replicated chromosomes are segregated into individual nuclei (mitosis), and the cell splits into two (cytokinesis). If organisms produced reproductive cells through mitosis instead of meiosis, they would have two sets of chromosomes. Esta distribución permite que se produzca la recombinación genética. interphase.
