diploid and genetically different from one another
B
diploid and genetically identical to the parent cell

D
haploid and genetically different from one another
Verified step by step guidance1
Recall that meiosis consists of two sequential divisions: meiosis I and meiosis II. Meiosis I reduces the chromosome number by half, while meiosis II separates sister chromatids.
Understand that at the end of meiosis I, the cells are haploid because homologous chromosomes have been separated, but each chromosome still consists of two sister chromatids.
During meiosis II, the sister chromatids are separated into different daughter cells, similar to mitosis, but starting from haploid cells.
Because of crossing over during prophase I, the chromatids are not identical, so the resulting daughter cells after meiosis II are genetically different from one another.
Therefore, the daughter cells at the end of meiosis II are haploid (one set of chromosomes) and genetically different from each other due to recombination and independent assortment.
