Down syndrome is  caused by the nondisjuction of the chromosome 21.

Non-disjunction of chromosomes refer to a situation in which chromosomes do not separate. When this occurs, an individual will have an abnormal number of chromosomes which results in a disorder such as the Down syndrome.

Disjunction of chromosomes occurs during the phase of meiosis called anaphase. Non-disjunction of chromosomes results in a phenomenon whereby a pair of chromosomes go to the same daughter cell.

Down syndrome results from nondisjunction during meiosis, resulting in uneven distribution of chromosomes.
