Q:

What are the products of meiosis?

A:

Quick Answer

Meiosis is a cell division process that occurs twice to produce four haploid daughter cells, according to Biology4Kids. Meiosis I occurs first and creates two daughter cells, and then meiosis II begins and creates two more daughter cells.

Full Answer

Meiosis is a cell division process that occurs when an organism is ready to reproduce, states Biology4Kids. The steps of meiosis are similar to the steps of mitosis, another type of cell division that occurs during growth and development of an organism. Meiosis begins with meiosis I. During this process, the cell undergoes prophase, metaphase, anaphase, telophase and interphase and creates two haploid daughter cells. Haploid cells contain only half of the number of chromosomes an organism needs to survive.

During meiosis I, crossing over occurs within the DNA. Crossing over allows genes to cross over to other chromosomes and mix themselves up, explains Biology4Kids. It is a process that adds diversity and variability to the gene pool of the organism. During meiosis II, the cells from meiosis I undergo prophase, metaphase, anaphase and telophase. After telophase of meiosis II, the cells begin to pinch inward and separate. At the end of meiosis II, there are four haploid cells known as gametes.

  • Q:

    How do I describe meiosis?

    A:

    Meiosis is the process in which cells divide to produce sex cells. Meiosis takes a single cell and divides it into four different cells with half of the necessary chromosomes for human development. Meiosis creates both egg and sperm cells.

  • Q:

    Why is meiosis important to living things?

    A:

    Meiosis is important to eukaryotes, such as plants, animals and fungi, because it is the method by which they produce sex cells. The ability to produce sex cells, and therefore reproduce sexually, increases the genetic diversity of the population. This increased genetic diversity provides a greater pallet of mutations on which natural selection can act.

  • 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:

    When does meiosis occur in humans?

    A:

    Meiosis in humans happens before birth in females, and constantly after puberty in males. Meiosis is the production of gametes, the cells used in sexual reproduction, and females possess nearly their full complement of partially developed eggs at birth. Males, on the other hand, don't even begin producing sperm until puberty, after which they create tens of millions to billions per day.
