Dear Manisha,
Chromosomal aberrations of the bone marrow (gaps, terminal deletions and breaks, fragments, inter-chromosomal fusions and sister-chromatid union) are studied in this paper:
Mutat Res. 2011 Nov 1;716(1-2):20-6. doi: 10.1016/j.mrfmmm.2011.07.016. Epub 2011 Aug 5.
Chromosomal aberrations in the bone marrow cells of mice induced by accelerated (12)C(6+) ions.

Dear Manisha,
It depends, as different methods allow to identify different types of aberrations. At metaphase stage you could identify some types of aberrations, but at anaphase-telophase stage this set of types will be different. Different staining techniques could also help to determine some types of aberrations. So, it seems, you need to decide what kind of aberration you are interested in.
