Scope note: Cromosomas metacéntricos producidos durante la MEIOSIS o MITOSIS cuando el CENTRÓMERO se divide transversalmente en lugar de hacerlo longitudinalmente. Los cromosomas resultantes tras esta división anormal son un cromosoma que tiene los dos brazos largos del cromosoma original, pero no brazos cortos, y otro cromosoma que tiene los dos brazos cortos y no tiene brazos largos. Cada uno de estos isocromosomas constituye una duplicación y deleción simultánea.
