The pan genome of a species is the genomic content that is
A) common to all strains of the same species.
B) present in one or more strains of the same species.
C) shared with all other prokaryotes.
D) hypothetical or uncharacterized genome content of a species.

Question

Quizplus · Accepted Answer

The pan genome of a species includes all of the gene families that are present in one or more strains of the same species, but not necessarily in all strains. This can vary widely between different isolates of the same species, making the pan genome a useful tool for understanding genetic diversity and evolution within a species. Option A is incorrect because the core genome is the genomic content that is common to all strains of the same species. Option C is incorrect because the pan genome only describes the genomic content of a single species, not all prokaryotes. Option D is incorrect because the pan genome refers to actual genomic content, not hypothetical or uncharacterized content.
