Identify the chromosomal aberration from the given diagram

Options

  1. ADeletion
  2. BDuplication
  3. CInversion
  4. DTranslocation

Correct answer

D. Translocation

Step-by-step solution

Based on the given diagram, the original chromosome has the gene sequence A-B-C-D-E-F-G-H. After the chromosomal aberration, the new sequence is M-N-O-C-D-E-F-G-H. The segments A and B have been replaced by entirely new segments M, N, and O. The presence of these new genes indicates that a segment from a non-homologous chromosome has been attached to this chromosome. The transfer of a chromosomal segment to a non-homologous chromosome is known as translocation. Therefore, the diagram illustrates translocation. Answ
