The process of dividing the preexisting cell into two or more daughter cells is called cell division. Meiosis and mitosis are two types of cell division. Mitosis divides one diploid mother cell divides into two diploid daughter cells whereas meiosis divides one diploid mother cell divides into four haploid daughter cells. This note gives brief introduction to cell division and their types.
Meiosis is reductional division, which takes place in reproductive cell. It is divided into meiosis I and meiosis II. Meiosis I is divided into prophase I, metaphase I, anaphase I, telophase I and mitosis into prophase II, metaphase II, anaphase II, and telophase II. This note has detail information on different stages of meiosis cell division.
Mitosis is divided into interphase, prophase, metaphase, and telophase. Mitosis cell division helps in asexual reproduction, growth, healing wounds and genetic stability. This note has description on how mitosis division occurs in living cell. It has detail information of different stages of mitosis.
The mechanism which fixes the sex of an individual when it begins life is known as sex determination. Sex is determined at the time of fertilization when the male gamete and female gametes fuse together.
