Detailed explanation-1: -The term ‘pangenome’ was defined with its current meaning by Tettelin et al. in 2005; it derives ‘pan’ from the Greek word , meaning ‘whole’ or ‘everything’, while the genome is a commonly used term to describe an organism’s complete genetic material. Tettelin et al.
Detailed explanation-2: -The pan-genome represents the entire set of genes within a species, consisting of a core genome-containing sequences shared between all individuals of the species-and the ‘dispensable’ genome.
Detailed explanation-3: -Additionally, many bacterial species are defined by a pan-genome. This means that different strains may contain distinct sets of genes, resulting in a species with a genetic repertoire that far exceeds that of any single genome.
