Solution

Answer :

A. This is a duplication mutation. This occurs when a section of chromosomes gets duplicated resulting in the increase in the dosage of genes. These duplications may arise in a variety of ways such as tandem duplication, displaced duplication. Ex: Bar eye in Drosophila.

B. This is the inversion mutation. occurs because of the two breaks in the chromosomes and essentially involves occurrence of breakage and reunion. During inversion a part of chromosome or set of genes are rotated by 180⁰ on its own axis. If the inverted area includes the centromere it is called pericentric inversion and if the centromere is not included it is termed as paracentric inversion
