What chromosome change resulted in the following sequences of the
chromosome?
(a) HIJKNM.LOPQ
(b) HIJKL.MNONOPQ
(c) HIJKLLK.MNOPQ
(d) HIJKL.MNCDEFG

Answer 1

your question is wrong only A T C G is the gene sequences

Answer 2

The correct answer for your question is option (A)-HIJKNM.LOPQ

In this case it can be the result of translocation where two non-homologous chromosomes have exchanged their parts. This may cause genetic disease when considered.

The option B contains a duplication of NO part.

The option C contains the inverted duplication of KL part.

The option D contains the translocation like the first option but in a wrong order.
