Which statement is NOT true about mitosis? Mitosis produces two daughter cells that contain the same kinds of chromosomes as the parent cell. Mitosis uses a diploid (2n) parent cell to form daughter cells containing a haploid number ?of chromosomes. Mitosis is involved in development of a fertilized egg into a multicellular organism. Mitosis is
