Question

the gene sequence of a chromosome is HIJKL.MNOPQ.What is the gene sequence for following sequence of the chromosome?
(a) HIJKNM.LOPQ.
(b) HIJKL.MNONOPQ
(c) HIJKLLK.MNOPQ
(d) HIJKL.MNCDEFG

Answer 1

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
