Question

Each mature sperm cell contains ______ (number) chromosomes. Upon fertilization of the secondary oocyte. It completes meiosis II to become an ovum, which has the same number of chromosomes as the mature sperm cell.

Answer 1

Answer:

The correct answer is - 23 (haploid).

Explanation:

Each mature sperm cell is a gamete that is produced by the meiosis type of cell division. Meiosis is the cell cycle that produces four cycle with the half chromosome in number than that of the parent cell. Humans have 46 chromosomes in but as explained the sperm or the gamete have only of that which is 23.

The same goes for ovum which is form by the meiosis second process from oocyte which is basically the egg cell. Both sperm and the ovum fuse to fertilize.

Thus, the correct answer is - 23 (Haploid)
