It's a sort of cell-division in which the cell's number of chromosomes is divided in half. This means the cell produced from meiosis has 23 chromosomes instead of the normal 46. This is used in the creation so-called gametes, the cells which we use for reproduction.
For example, the male gamete - the sperm cell - has 23 chromosomes. When the sperm cell joins up with the female egg cell, the two combine and the resulting cell-divisions produce cells with "normal" number of chromosomes: 46.
Meiosis should not be confused with mitosis.

What Meiosis occurs in .?
meiosis occurs in the overies and the testies.....there is 2 stage of meiosis...meiosis 1 and meiosis
Physical process that occurs more than once during meiosis?
Crossing over: a physical process that occurs during meiosis in which homologous chromosomes exchange genetic material, increasing genetic diversity.
In what structure does meiosis occur in bryophytes?
Meiosis in bryophytes occurs in specialized structures called sporangia. These sporangia house the cells that undergo meiosis to produce spores, which are later dispersed and germinate into the gametophyte stage of the bryophyte life cycle.
Which phase occurs before mitosis or meiosis?
The interphase occurs before both mitosis and meiosis. During interphase, the cell grows, carries out normal metabolic activities, and duplicates its DNA in preparation for cell division.
Does meiosis occur in males or females?
Meiosis occurs in both males and females. In males, meiosis takes place in the testes to produce sperm cells, while in females, meiosis occurs in the ovaries to produce egg cells.
What Meiosis occurs in .?
meiosis occurs in the overies and the testies.....there is 2 stage of meiosis...meiosis 1 and meiosis
What stage occurs when crossing over occurs in meiosis?
Prophase I of Meiosis.
What occurs in meiosis i that does not occur in meiosis ii?
DNA is copied.
What structure does meiosis occur in bryophyte?
Meiosis occurs in the sporophyte.
What type of cells does meiosis occur in?
Meiosis occurs in gametes or reproductive cells.
Asexual reproduction occurs in?
meiosis
What occurs inside the gametangium?
Meiosis
Meiosis only occurs in?
nucles
Where does meiosis occur in humans?
In human males, meiosis occurs in the sperm sex cells. This usually occurs in the testes of the human male.
When does crossing occurs in meiosis?
Crossing over occurs during Prophase I.
What happens in meiosis 1 that does not occurs in meiosis 2?
DNA is copied (for novanet cheaters)
How many times does meiosis occur in a human?
Remember that meiosis occurs during the production and maturation of gametes so it occurs very often! In males, it occurs virtually throughout their whole life and in females, meiosis I completes at every ovulatory cycle until menopause and meiosis II completes with fertilization.
