Q:

What is the importance of meiosis?

A:

Quick Answer

The importance of meiosis is that it enables genetic diversity. Unlike the asexual form of cellular division, mitosis, meiosis allows chromosome pairs with the same genes, called homologous chromosomes, to exchange pieces in a process called recombination. This enables chromosome pieces from the female parent to combine with those of the male parent.

Full Answer

The advantage to meiosis is that the genetic diversity it produces among sexual organisms can help make a species population more stable by producing a wider variety of traits for the process of natural selection to act upon. Meiosis relies upon processes that are similar to those occurring during mitosis during cell division, but several, such as recombination, occur only in meiosis.

  • Q:

    What is the outcome of meiosis?

    A:

    The process of meiosis results in four cells that possess half of the chromosomes of the original cell. This occurs in cells that possess two chromosome sets, which happens in organisms that reproduce sexually. The cellular biology of reproduction requires two gamete cells to interact.

  • Q:

    What are the events of meiosis?

    A:

    The main events of meiosis include prophase, metaphase, anaphase and telophase. A cell in meiosis goes through two divisions, meiosis I and meiosis II, in which each division consists of the same stages to produce gametes or sexual reproduction cells.

  • 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.

  • Q:

    What happens during meiosis?

    A:

    During meiosis, a cell divides into four daughter cells called gametes that are used during sexual reproduction. A cell grows larger during interphase, then goes through multiple other steps, such as prophase and metaphase, before finally dividing into four gametes.
