Detailed explanation-1: -There are two major events that occur in both mitosis and meiosis i.e. the division of nuclear material called karyokinesis and the division of cytoplasm called cytokinesis. Karyokinesis means the process of division of the nucleus during mitosis or meiosis.

Detailed explanation-2: -Mitosis produces two diploid (2n) somatic cells that are genetically identical to each other and the original parent cell, whereas meiosis produces four haploid (n) gametes that are genetically unique from each other and the original parent (germ) cell.

Detailed explanation-3: -Which of the following does NOT occur in both mitosis and meiosis? Splitting of homologous pairs of chromosomes.

Detailed explanation-4: -The condensation of interphase chromatin to form the compact chromosomes of mitotic cells is a key event in mitosis, critical in enabling the chromosomes to move along the mitotic spindle without becoming broken or tangled with one another.
