Most people have 46 chromosomes, or 26 pairs of chromosomes. Individuals with Down syndrome have 47 chromosomes. They have 25 ordinary pairs. The 21st pair of chromosomes becomes three chromosomes as opposed to a pair so there is an extra 21st chromosome. Sometimes there is only a part of an extra 21st chromosome present.
