The each chromosome makes the copy of itself before the M Phase in mitosis because the resultant daughter cell the chromosomes is genetically identical.
<u>Explanation:</u>
The parent cell in the chromosomes make the copy before mitosis. The copy is occurred during the S phase of inter phase. During the mitotic M phase, the cell divides the copied DNA and cytoplasm to make two new cells.
M phase involves two distinct related processes which is mitosis and cytokineses ;the cell growth steps into the new stage and cellular energy is developed on the division in the phase

Answer:
c. each primary spermatocyte produces 4 gametes while each primary oocyte produces one gamete.
Explanation:
The primary spermatocytes are the diploid cells that enter the process of meiosis during spermatogenesis. Meiosis-I in one primary spermatocyte produces two haploid secondary spermatocytes. Both of these secondary spermatocytes enter the second meiotic division and form a total of four spermatids.
On the other hand, the primary oocyte enters the process of oogenesis and gives rise to one secondary oocyte and a first polar body. Both of them are haploid. Meiosis-II in the secondary oocyte forms an egg cell and second polar body. Therefore, only one female gamete is produced by one primary oocyte.
