This Slide conatain information about chromosomal abnormalties

5. Types
Numerical - change in no.
Structural – change in structure

6. Structural abnormalities
1. Translocations
2. Deletions
3. Insertions
4. Inversions
5. Duplication

7. Translocation
Segments from two different chromosomes are
exchanged

8. Deletions
A portion of chromosome
is missing or deleted

9. Duplication
A portion of chromosome is duplicated

10. Insertions
A segment of chromosome breaks off,
and attaches to another chromosome

13. 1.Artificially:
It can be produces by
X-irradiation in laboratory,
Chromosome break into pieces, these pieces
reattach in inverted form.

17. Morphology of the chromosome will not be
