Duplication and Translocation pair is a chromosomal aberration.
- Option (c) is correct.
- The chromosomal aberration is of 4 types.
- They are:
- Duplication - a segment of the chromosome is repeated twice (duplicated).
- Inversion - a section of the chromosome gets changed by rotation at 180°.
- Deletion - a loss of a segment of a chromosome.
- Translocation - transfer of a section of one chromosome to a non-homologous chromosome.
