no, it has half the number

If an egg cell contains 50 chromosomes, then a sperm cell from the same species would also contain 50 chromosomes, as both egg and sperm cells are haploid and contain half the number of chromosomes of the diploid organism. Therefore, when they combine during fertilization, they restore the diploid number, which would be 100 chromosomes in this case.
Meiosis and mitosis are types of cell division that involve the replication and division of chromosomes. Meiosis produces sex cells (eggs and sperm) with half the number of chromosomes as the parent cell, while mitosis produces identical cells with the same number of chromosomes. Sex cells have either X or Y chromosomes, determining the individual's sex.

A sperm cell from the same species would also contain 50 chromosomes. When an egg and sperm fuse during fertilization, the total number of chromosomes in the resulting zygote will be the sum of the chromosomes from the egg and sperm, which would be 100 in this case.

15. A sperm cell is an example of a haploid cell. Two haploid cells combine to form a diploid cell, of which a heart cell is an example.

A sperm cell is the male sex cell. As such it only carries 1/2 of the number of chromosomes of a regular cell. This is because it fuses with the female sex cell to form a complete set of chromosomes. Essentially, where the number of chromosomes in the muscle cell is 2n, the sperm cell only has n chromosomes.
Yes. In an individual, almost all cells contain DNA (Red Blood Cells do not). That DNA is tightly wound like you would twist a drawstring, and kept tightly coiled as chromosomes. Since chromosomes can be found in a cheek cell, a liver cell (hepatocyte), and almost all other cells, they all contain the same chromosomes, which inevitably have the same genes. What makes cheek cells different from liver cells is which genes are turned on and off. Cheek cells have different genes turned on compared to liver cells.
46 chromosomes. The only cells in the human body that do not contain 46 chromosomes are specialist cells which have no cell nucleus (eg a human red blood cell) and reproductive cells, which only contain 23 chromosomes. Thus the cheek cell of the animal would be no different from any other cell in its number of chromosomes and would contain the full number of chromosomes for that animal.
