Year three was a hell of a lot harder than year one in primary school. lol you are taking to the extreme but i have heard some freinds say that second year is the hardest for some reason. (Original post by Aspiringlawstudent).
In mitosis a cell divides to form two identical daughter cells. It is important that the daughter cells have a copy of every chromosome, so the process involves copying the chromosomes first and then carefully separating the copies to give each new cell a full set.
Mitosis can produce two _haploid_ daughter cells, if it is a haploid cell undergoing mitosis. There is no reason for it to be only diploid cells that undergo mitosis, and it is in fact not the case. The key point is that the chromosome number does not change. Mitosis _DOES NOT_ occur in all organisms.
