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:

    Why is meiosis important?

    A:

    Meiosis is important because during sexual reproduction, it ensures that all produced organisms have the correct number of chromosomes. It is also responsible for producing genetic variations during the process of recombination, and it repairs some genetic defects.

  • Q:

    What is the purpose of meiosis?

    A:

    Meiosis is the process of cell division that creates offspring in sexually reproducing organisms, explains a University of Illinois at Chicago website. Unlike during mitosis, meiotic cell division starts with double the number of chromosomes in diploid parent cells. Meiosis cuts this number in half forming two haploid daughter cells. When these daughter cells combine and undergo fertilization, a zygote is created and the cell begins to develop.

  • 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:

    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.
