A: The geneticist we met with after Chase was born told us briefly that our chances of having another child with Ds was 1%...but not truly based on numbers, just that it had to be higher than nothing. I didn't really understand that. Basically, I think that it means that since Ds is a genetic anomoly, and Chase has the regular old fluke-ish Trisomy 21, that our chances don't really change, but they have to assign us a number just because. If anyone else has a better answer than that, I'd love to hear it.
As far as Chase goes, I believe that most males with Ds are sterile. So his chances of passing it on are close to nothing. I have heard stories of women with Ds giving birth to typical babies. I don't know what the real odds are on that, and I am too tired to look up any genetics information just now :)
