Pan Genomics

The Pan Genome considers the aspects of the “core genome” which represents in all the strains, “dispensable genome” also present in two or more strains and “unique genome” specified to single strains. The importance of the pan-genome turns up in an evolutionary framework, especially with relevance to Metagenomics, but is also used in an extensive genomics framework.  The two types of Pan Genomes are Closed Pan Genome which has insufficient genes added per additional sequenced genome whereas Open pan Genome have sufficient genes added per additional sequenced genome.
