Q:

What is produced by meiosis?

A:

Quick Answer

Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell. Meiosis produces four gamete cells. Meiosis is required to produce egg and sperm cells for sexual reproduction.

Full Answer

Though meiosis reduces the number of parent cells by half, the cells are restored in the offspring after the sperm and the egg unite according to Scitable by Nature Foundation. Meiosis I is the first meiotic division, which begins with prophase I. The complex of DNA and protein, which is known as chromatin, condenses to form chromosomes. Meiosis II is a mitotic division of the haploid cells produced in meiosis I. After meiosis is complete, there are four haploid daughter cells that eventually become sperm or egg cells.

  • Q:

    How many chromosomes are in each daughter cell at the end of mitosis?

    A:

    In human cell mitosis, each daughter cell will have the same number of chromosomes as the parent cell, which is 46 chromosomes. If the parent cell is diploid, it has two sets of chromosomes, or a total of 46. If it is haploid, such as sperms and eggs, they have one set of chromosomes, or just 23.

  • Q:

    What is the difference between mitosis and meiosis?

    A:

    Mitosis is the process where one cell divides into two cells with the same number of chromosomes as the original cell, while meiosis is the process where one cell divides into four cells with half the number of chromosomes as the original cell. The processes have very similar steps. In humans, all cells undergo mitosis except the gametes, which undergo meiosis.

  • Q:

    Why is meiosis important for sexual reproduction?

    A:

    Meiosis is important because it reduces the number of chromosomes by half allowing sexual reproduction to occur. If meiosis did not happen, the cell would have too many DNA pairs. This would result in the death of the cell or other life-threatening complications with offspring.

  • Q:

    Where does meiosis occur?

    A:

    Meiosis occurs in the reproductive organs of all males and females. The process of meiosis results in the formation of gametes. Gametes are the reproductive cells called sperm in males and ova or eggs in females.
