I strongly disagree with the above, and think this was an irresponsible
post. This isn't theory on a first year exam. This is a question of
potential life or death of a real fetus. The real problem is that
nobody can say whether this child will be normal. There isn't a simple
way of determining whether, or how much DNA was lost during the
translocation process.
