Metaphase

The phase of mitosis, or cell division, when the chromosomes align along the center of the cell. Because metaphase chromosomes are highly condensed, scientists use these chromosomes for gene mapping and identifying chromosomal aberrations. See also cell, chromosome, gene, mapping

A stage in mitosis or meiosis during which the chromosomes are aligned along the equatorial plane of the cell.

Stage of mitosis or meiosis (following prophase and preceding anaphase ) during which the chromosome s, or at least the kinetochores, lie in the central plane of the spindle. The stage of maximum chromosome condensation, at which karyotypes are generally described. In the first division of meiosis, metaphase represents the stage at which meiotic analysis is generally performed.

A stage of mitosis where chromosomes are firmly attached to the mitotic spindle at its equator but have not yet segregated toward opposite poles.
