The observations would be
a) HIJKNM.LOPQ- Translocation is an abnormality in the chromosome that is caused by the rearrangement of parts between nonhomologous chromosomes
b) HIJKL.MNONOPQ- Duplication is a major mechanism through which the new genetic matter is generated during molecular evolution
c) HIJKLLK.MNOPQ- Inversion is termed as when the region between the breaks rotates 180 degrees before rejoining with the two end fragments
d) HIJKL.MNCDEFG- Translocation
