Down's Syndrome is a type of trisomy - they have an extra copy of chromosome 21.

1. If somebody with some form of aneuploidy has a child, is it heritable at that point?
2. Sometimes, closely related species seem to have vastly different amounts of chromosomes. Do we know why this can happen? I mean, this isn't one of those slow development things that makes sense to me. How do extra sets of chromosomes appear (or spare sets disappear)?
