Hereof, why is it important for gametes to have half the diploid number of chromosomes?
Why is it important that gametes have half the number of chromosomes than the rest of the body cells ? -because when sperm and egg fuse, the zygote formed will contain the normal diploid number of chromosomes characteristic of the species.
Similarly, why is it important that gametes have only one set of chromosomes? So that when two gametes come together, their chromosomes combine to make to diploid (2n) number of chromosomes.
Also to know is, why do gametes only have 23 chromosomes?
Meiosis is cell division for gametes, or reproductive cells (sperm and egg). We have 23 pairs of chromosomes (which contain our DNA), so 46 in total. The reason is because in a regular cell, 23 chromosomes come from the mother and the other 23 come from the father.
