Question
The first child has chromosomal balanced translocation and is now two years old. The child’s intelligence is normal, but there is a slight delay in motor development, and the appearance is different from that of most people. Can we apply for a second child? What is the success rate?
Answer
The child’s intelligence is currently unaffected, and there are no obvious deformities in appearance. If both parents’ chromosome tests confirm the abnormality, there is a chance to apply for a second child. However, the genetic probability of chromosomal abnormalities is not absolute and depends on the specific situation.
