  supertype:  cell_division__cellular_division  the process in reproduction and growth by which a cell divides to form daughter cells
  part:  anaphase  karyokinesis  metaphase.phase_of_cell_division  prophase.phase_of_cell_division  segregation.organic_process  telophase.phase_of_cell_division
  subtype:  nondisjunction  meiosis in which there is a failure of paired homologous chromosomes to separate; results in an abnormal number of chromosomes in the daughter cells
