The reason that why there are many more people with an extra chromosome 21, which causes Down syndrome, than people with an extra chromosome 3 or chromosome 16 when non disjunction is a random event. Introduction: Down syndrome is a genetic disorder which occurs due to the presence of an additional set of chromosome 21 that is trisomy 21. This disbalance of the distribution of chromosome occurs due to the failure of separation of chromosome 21 during the stage of meiosis I. This situation is called as non disjunction where chromosome segregation does not occur properly.
