What Is The End Result Of Meiosis?
Meiosis is one of the essential stages of life cycle of a plant or animal. It is the process in which the cell divides into two cells. In meiosis, the cell undergoes two rounds of mitosis.
Meiosis I
Meiosis is a type of cell division that occurs during gametogenesis (the formation of germ cells) and produces haploid gametes, such as sperm or eggs. During the first meiotic division, the homologous chromosomes separate from each other and form two daughter nuclei. This division is called meiosis I.
Meiosis II
The second meiosis divides the remaining chromosomes into four groups, producing four daughter nuclei. This is known as Meiosis II.
After meiosis I, the genetic material of the two daughter cells is combined together to produce new diploid cells. These cells then go through mitosis, or cell division, where they start dividing at random. After mitosis, the resulting cells become either spermatogonia or oogonia. Spermatogonia undergo another round of meiosis to produce spermatocytes. Oogonia undergo meiosis once more to produce oocytes.
The End Result of Meiosis:
The end result of meiosis is to produce four kinds of gametes (eggs and sperm). The four gametes will fuse to form a zygote. This zygote will develop into an embryo.
Will the cells be identical ?
Though the number of chromosomes are same but the genetic constitution of the chromosomes in each cell is not same ,because of crossing over and random orientation of bivalents at the metaphase-I stage.
