Aneuploidy
|
In cells, too many or too few chromosomes relative to the parental number.

Polyploidy
|
Having three or more of each chromosome type characteristic of a species.

|
Nondisjuction
|
Failure of sister chromatids or homologous chromosomes to separate during meiosis or mitosis. Daughter cells end up with too many or too few chromosomes.
