There are three types of down syndrome, each with separate causes, and trisomy 21 is the most common of these. in trisomy 21, a random error in cell division occurs. this error is called "nondisjunction." typically, each pair of chromosomes from the father and mother separate at conception, to provide one half of the embryo's pairs of chromosomes.

Here's a thought—if your risk is high, you could learn something about down syndrome just in case, or maybe do the screening even if you're not particularly older. then if you find out you have a higher chance than you thought, but you're not comfortable with amniocentesis, you can still learn a few things that could help if your baby is born.
