Answer
A limitation of gram staining is that it only classifies bacteria into two categories: one with a thick peptidoglycan cell wall and one with a thin cell wall. It offers little insight on the genomes of the bacteria or the particular function of its proteins, two traits that would help tremendously in determining the phylogenetic relationships between the prokaryotic organisms.
