Difference between mitosis and meiosis
Answers
Answer:
Mitosis involves the division of body cells, while meiosis involves the division of sex cells. The division of a cell occurs once in mitosis but twice in meiosis. Two daughter cells are produced after mitosis and cytoplasmic division, while four daughter cells are produced after meiosis.
In mitosis, the genetic material (DNA) in a cell is duplicated and divided equally between two cells. The dividing cell goes through an ordered series of events called the cell cycle. The mitotic cell cycle is initiated by the presence of certain growth factors or other signals that indicate that the production of new cells is needed. Somatic cells of the body replicate by mitosis. Examples of somatic cells include fat cells, blood cells, skin cells, or any body cell that is not a sex cell. Mitosis is necessary to replace dead cells, damaged cells, or cells that have short life spans.
Meiosis is the process by which gametes (sex cells) are generated in organisms that reproduce sexually. Gametes are produced in male and female gonads and contain one-half the number of chromosomes as the original cell. New gene combinations are introduced in a population through the genetic recombination that occurs during meiosis. Thus, unlike the two genetically identical cells produced in mitosis, the meiotic cell cycle produces four cells that are genetically different.
Answer:
following are some differences between mitosis and meiosis:-
1) mitosis involves the division of body cells while meiosis involves the division of sex cells.
2) the division of a cell occurs once in mitosis but twice in meiosis
3) two daughter cells are produced after mitosis while four daughter cells are produced after meiosis
4) tetrad formation occurs in meiosis but not in mitosis
5) daughter cells resulting from mitosis are diploid while those resulting from meiosis are haploid.
