The total number of chromosomes is reduced by half during both mitosis and meiosis.

Explanation:

All statements are true except this: The total number of chromosomes is reduced by half during both mitosis and meiosis. The total number of chromosomes is reduced by half only through meiosis.

Mitosis is a process of cell division by which a mother cell generates two cells with its same genetic content. For example, if the mother cell is diploid, the daughter cells will also be diploid.

Meiosis is a process of cell division by which a mother cell (germline cell) generates four cells (gametes), each with half of the mother's genetic content. For example, if the stem cell is diploid, the daughter cells will be haploid.
