Down's syndome is a chromosoal disorder caused by having 3 copies of chr an extra chromosome on chromosome 21 (referred to as trisomy 21), giving a total of 47 chromosomes instead of the normal 46 in humans. This extra chromosome copy affects how the brain and body develops, thus affecting both physical development and intellectual ability. Although individuals with Down's syndrome behave and look similar, their intellectual capability varies from mild to moderately low.
