How many chromosomes does a human sex cell have?
23 unpaired Chromosomes.
Human sex cells are :
- Sperm : Male sex cell.
- Ovum : Female sex cell.
Each "human body cell" has 46 chromosomes. But human sex cells have 23 unpaired chromosomes in each cell. Sex cells are created by a special type of cell division, Meiosis.
This pictures are showing, how sex cells (sperm and egg or ovum) are created by meiosis. They have "n" chromosome which means 23 in number. When two sex cells fuse together to create a Zygote, this zygote has "2n" chromosomes. Which means it has 46 chromosomes.
