Down syndrome is when you have a trisomy of chromosome number 21. So that means they have 47 chromosomes.
An older name for Down Syndrome is Mongolism. That was considered a racist term because it made fun of the features of people from Mongolia. Its use was dropped in 1965 after a delegate from Mongolia asked that the name be dropped as a medical term.
