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:

    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.

  • 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:

    What is the difference between meiosis 1 and meiosis 2?

    A:

    The essential difference between meiosis I and meiosis II is in purpose. Meiosis I is dedicated to forming two haploid cells from one diploid cell, while meiosis II is meant to split the sister chromatids in the haploid cells produced in meiosis I, creating four daughter cells. Meiosis I also recombines, or shuffles, genes on each pair of chromosomes. Meiosis I and meiosis II happen in succession.
