Meiosis is a biological process in plants and animals, as well as in some microorganisms. The process leads to the division of the nucleus in a cell in organisms that are capable of sexual reproduction. Meiosis is pivotal to reproduction or procreation.

Meiosis is a special type of cell division. Unlike mitosis, the way normal body cells divide, meiosis results in cells that only have half the usual number of chromosomes, one from each pair. For that reason, meiosis is often called reduction division. birds in the sky you know how i feel song

The G 1 phase (the “first gap phase”) is focused on cell growth. During the S phase—the second phase of interphase—the cell copies or replicates the DNA of the chromosomes. birds in the sky lyricsWebMeiosis is the great process that shuffles the cell's genes around. Plants do it, animals do it, and even fungi do it (sometimes). Instead of creating two new cells with equal numbers of chromosomes (like mitosis), the cell does a second division soon after the first. That second division divides the number of chromosomes in half. birds in the sky lyrics michael buble
