Q:

What are the events of meiosis?

A:

Quick Answer

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.

Tetrads, a connected grouping of chromatids, develop with the breakdown of DNA that occurs in prophase. In metaphase, genetic recombination and spindle formation occurs. During anaphase, the tetrads split apart into two pairs pulling to opposite sides of the cell. In telophase, the nuclear envelope holding the chromosomes forms to create a haploid. The process repeats again, but the two opposite sides with the chromosomes develop a cleavage furrow between the two pairs, and the one cell eventually divides into two 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.

  • 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 happens in meiosis 1?

    A:

    During meiosis 1, a diploid cell's chromosomes segregate and produce four haploid cells. It is the completion of this phase that leads to genetic diversity.

  • Q:

    What are the products of meiosis?

    A:

    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.
