Q:

What is the importance of meiosis?

A:

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.

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:

    Why is crossing over important in meiosis?

    A:

    Crossing over in meiosis results in genetic recombination, which is responsible for the genetic diversity of a population. Genetic recombination and natural selection are the driving forces behind evolution. It causes most of the differences between parents and their offspring and differences between siblings.

    What is the function of meiosis?

    A:

    The function of meiosis is for sexual reproduction as meiosis creates new cells for an organism. Meiosis has two cell divisions known as meiosis I and meiosis II.

  • 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 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.
