Homologous chromosomes form pairs during both mitosis and meiosis. chiasma form during meiosis i but not during mitosis. the sister chromatids of replicated chromosomes separate during both mitosis and meiosis ii. the total number of chromosomes is reduced by half during both mitosis and meiosis.

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.
