Identify the chromosomal aberration from the given diagram
Identify the chromosomal aberration from the given diagram
Options
- ADeletion
- BDuplication
- CInversion
- 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The segments A and B have been replaced by entirely new segments M, N, and O. The presence of these new genes indicates that a segment from a non-homologous chromosome has been attached to this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.
