Summary Introduction
Introduction :
The cell division is of 2 types, mitosis and meiosis. The mitosis is the process of the cell division, which occur in all the somatic cells present in the body of the multicellular organism. The meiosis is the cell division, which occurs to produce the haploid germ cells.
