Summary Introduction

Genome encompasses all the information essential for the survival of that organism. Heritable modification in the nucleotide sequence of the genome that is passed from parent to next generation (progeny cells) is regarded as mutation. Such mutations may result in altering the characteristics of that organism. Selectable mutations confer some advantage on the mutant possessing them, whereas others are referred to as non-selectable mutations. Such non-selectable mutations may result in a remarkable modification in the organism’s phenotype.
