| − | '''Metaphase''' is the phase of [[mitosis]], or cell division, when the [[chromosome]]s align along the center of the cell. Because metaphase chromosomes are highly condensed, scientists use these chromosomes for gene mapping and identifying chromosomal aberrations. | + | '''Metaphase''' are the phases of [[mitosis]] (of which there is one phase) and [[meiosis]] (of which there are 2 phases, metaphase 1 and metaphase 2), or cell division, when the [[chromosome]]s align along the center of the cell.
