A. Meiosis goes through two divisions and has crossing over to increase genetic variation. (This is why the result are four daughter cells).
B. Mitosis produces diploid cells with the same number of chromosomes as the parent cells, actually, the daughter cekks are geneticaly identical to the mother cell.
C. Alike meiosis, mitosis goes through one division giving two daughter cells as a result.
D. Meiosis produces haploid cells called gametes (eggs and sperm) with the half the number of chromosomes as the parent cell because the first meiotic division is reductional.
