As far as I can tell, all the aliens you can meet in TS3 are unrelated. I have no idea who counts as the parents of an abduction baby now - but I'd sure like to find out. That method is interesting as well, because the child is pureblood and you still get to select it's traits as it grows (assuming you're a good parent). :D
