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.

    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.

    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.

    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 in humans?

    A:

    Arizona State University states that meiosis is how sexually reproducing organisms, including humans, produce gametes, or sex cells. Gametes are fundamentally different from the body, or somatic, cells of sexually reproductive organisms because gametes only have half of the genetic code in their nucleus. When two different gametes fuse and produce a zygote, their half-complements of genetic material combine to form a complete genome with the full complement of chromosomes.
