When does a cell go through meiosis?

Answer 1

First of all, most cells in the body divide through the process of mitosis, except for sex cells, sperm and eggs. They must divide through a different process, meiosis, because they must end up with half the number of chromosomes as a typical cell after they divide. Another word for a cell with half the normal amount of chromosomes is a haploid cell. Diploid cells are cells with the normal amount of chromosomes.

Meiosis occurs much more often in men, who are constantly reproducing sperm, whereas women are born with all the eggs they will ever have. Cells go through meiosis whenever they are in need of creating more haploid sex cells.

Answer 2

MEIOSIS I: This is basically like the PMATI of a regular mitosis. Pairs of chromosomes are lined up at the center of the cell and then pulled to each side. Meiosis is a bit different because there something called crossing-over happens with the DNA.

This crossing over is an exchange of genes. The genes are mixed up, not resulting in a perfect duplicate like mitosis. The cell divides, leaving two new cells with a pair of chromosomes each. Normally the cell would begin to go about its business of living and slowly duplicate the chromosomes for another mitotic division. Since this is meiosis, there is a very short interphase and division begins again.

Answer 3

A cell goes through meiosis during the formation of gametes (sperm and egg cells) in sexually reproducing organisms. Meiosis occurs in two rounds of cell division, resulting in four haploid daughter cells with unique combinations of genetic material.

Answer 4

The complete meiosis process in human males takes roughly seventy-four hours from start to finish. Meiosis in human females is much more complex.
