Mitosis. We can think about mitosis like making a copy of an instruction manual. Copy each page, then give one copy to each of two people. In mitosis, a cell copies each chromosome, then gives one copy to each of two daughter cells. With our instruction manual example, it is really important that each person gets one copy of every page. We don't want to accidentally give one person two copies of page four and one person zero copies of page four. And the copies need to be perfect. No misspellings, no deletions. Otherwise, we might not be able to follow the instructions and things could go wrong. This is also true with mitosis. We need each of our cells to receive exactly one copy of each chromosome, and each copy needs to be perfect, no mistakes, or the cells may have trouble following the genetic instructions. Fortunately, our cells have amazing systems to copy chromosomes almost perfectly and to make sure that one copy goes to each daughter cell. Still, very rarely mistakes in copying or dividing chromosomes are made, and these mistakes can have negative consequences for cells and for people.

Mitosis is a cellular process that replicates chromosomes and produces two identical nuclei in preparation for cell division.

Meiosis is the formation of egg and sperm cells. In sexually reproducing organisms, body cells are diploid, meaning they contain two sets of chromosomes (one set from each parent).
