Down's Syndrome is a genetic disorder caused by trisomy in chromosome 21, which is in turn a result of post-miotic nondisjunction occuring. Trisomy 21 is a rare conditon, occuring in one in six hundred children. However, this is more likely to decrease once a mother is over forty. A charcteristic of a child with this disease is mental retardation, a flattened nose, a long toungue and small hands and feet. These children also tend to have a shorter life span[1].
