Weba.) Each daughter cell produced during meiosis and mitosis is genetically identical to the parent cell. b.) In mitosis and meiosis I, homologous chromosomes move independently of each other. c.) Meiosis II is similar to mitosis in that sister chromatids of each chromosome separate. d.) WebAnswer (1 of 6): Yes, though generally it will not be detectable by classic mapping techniques since they carry the same DNA sequence.
