disjunction

The separation movement of members of pairs of chromosomes to opposite poles of a cell in the process of cell division.

disjunction

the separation of HOMOLOGOUS CHROMOSOMES to opposite poles during anaphase of nuclear division, particularly MEIOSIS. Abnormalities in disjunction (see NONDISJUNCTION can lead to a chromosomal mutation in which daughter cells possess too many or too few chromosomes. In humans extra AUTOSOMES can result in severely abnormal individuals (see DOWN'S SYNDROME, PATAU SYNDROME, EDWARDS'SYNDROME). See also TURNER'S SYNDROME and KLINEFELTER'S SYNDROME for disjunction abnormalities affecting the SEX CHROMOSOMES.
