Downs syndrome is a genetic abnormality caused by an extra chromosome, in simple terms - as a healthy individual you inherit 22 chromosomes from your mother and 22 from your father, so that's 44 altogether, 1 chromosome from each of your parents will combine to form 22 sets, in a person with Downs syndrome there is an extra abnormally shaped set of chromosomes. So in short a person with Downs syndrome has 23 chromosomes instead of 22.
