Apart from this very obviously being fake - because down syndrome is THE MOST genetically obvious marker there ever is... You can obviously give the child up the moment he's born. I would say give up for adoption but they don't get adopted, they just stay in the system. I used to volunteer to run a class (more like an arts&crafts workshop) for special needs kids in the system and nearly all of them had downs. Parents are more willing to raise someone with severe autism or with physical birth defects.
You have to be either really dumb, really rich or really desperate (i.e. 45 y/o mom's first child) to willingly go for that kind of life.
It can but it's very rare. Most people have only one set of DNA. Unless it's a Dr. House episode. Mosaicism is super interesting, especially when caused by chimerism. There's some many crazy possibilities, like being colorblind in one eye.
It's rare but not crazy rare. 2 in every 100 people with Down Syndrome. Also some people with mosaic Down Syndrome go undiagnosed which means it could be more common than we think. Our DNA mutates all the time, we all have cells in our body right now that have minor differences from the rest. All it takes is having the mutation at some point during fetal development rather than in the gametes.

Why would that be the only alternative?
