Meiosis is sometimes called reduction division. what does this mean and why is it important

Meiosis is a kind of cell division. It will lead to 4 daughter cells which each has only half of their chromosomes comparing to the parent. The end product has less chromosomes than the original that's why it's called reduction division.

Meiosis is important because the products are usually seen in gametes, which is sperms and eggs. If they get fertilized, they will form a zygote, and this is reproduction. Meiosis makes sure that the zygote has the right number of chromosomes, like half and half equals the correct amount chromosomes the organism should have. This also leads to diversity which is very important and a must in sexual reproduction.
