How many chromosomes are in each cell of your body?

Answer 1

The simple answer is 46.

The more complicated answer is "it depends". Humans have 23 different chromosomes, and you have two unique copies of each, one from your mother and one from your father. Therefore, you have 46 unique chromosomes, and most cells in your body have this number most of the time. However, because cells divide, certain cells may have different numbers of copies of these chromosomes. Cells undergoing mitosis (normal division) replicate their chromosomes in the S phase of the cell cycle. Therefore, between the S phase and the T phase when the cell is fully divided into two, there are 2 copies of each chromosome = 92. On the other hand, sex cells (sperm and egg) are produced by meiosis; one of these cells will join up with one of the opposite sex to make a zygote, which will grow into a baby. Each sex cell has 23 unique chromosomes, so that the zygote will have 46, two of each.

Answer 2

There are typically 46 chromosomes in each cell of the human body, with 23 pairs. This includes 22 pairs of autosomes and one pair of sex chromosomes.

Answer 3

23 pairs in each.
