An example of meiosis is when a chromosome reduces from a double cell to a single cell.
- the process of two consecutive nuclear divisions in the formation of germ cells in animals and of spores in most plants, by which the number of chromosomes ordinarily is reduced from the diploid, or double, number found in somatic cells to the haploid, or halved, number found in gametes and in spores
Origin of meiosisModern Latin from Classical Greek mei?sis from meioun, to make smaller from mei?n, less: see minor
