REASON:
Amoeba reproduces by the process of binary fusion which is an asexual mode of reproduction.
Since, in asexual method mitosis cell division takes place, same DNA material is transferred to the offsprings so no new traits and genes can be found in offsprings.
However in some case due to genetic drift or mutation, slight variations can be found in progeny.
But this is very exceptional.

Answer:
Somatic hypermutation is a process in which point mutations build up in the antibody V-regions of both the heavy and light chains.
This process occurs at rates that are about 106-fold higher than the background mutation rates observed in other genes.
It allows B cells to mutate the genes that they use to produce antibodies. This then ensures the B cells to produce antibodies that are better able to bind to bacteria, viruses and other infections.
