  1. In mitosis the daughter cells would have the same ploidy (2n) but the parent chromosomes prior to mitosis will already be double and be made up of 2 chromatids (=2 DNA molecules). At mitosis the chromosomes separate into their chromatids with each daughter cell receiving one chromatid from each and every chromosome (now called daughter chromosomes) - these will double again prior to further mitoses.

    In meiosis because there are 2 rounds of division, the daughter cells (4 of them per cell) will be haploid (n) and have one copy of one chromosome from each paired chromosome ( a chromatid = daughter chromosome)


  2. the amount of chromosomes in the daughtercell is always equal to the amount in the mothercell
