Quizplus · Accepted Answer

The Answer is Conventional karyotyping using chromosome banding is nevertheless still clinically important. That is so because molecular genetic methods such as array CGH are not suited to detecting balanced chromosome rearrangements in which there is no net gain or loss of DNA. Balanced translocations and inversions would normally be invisible to these methods, but they can be detected by chromosome banding.
