You are studying 12 new isolates from the human skin. The isolates have 16S rRNA sequences that are 97% similar and share important phenotypic traits. Their genomes have 55% of their genes in common. The isolates would most likely be A) classified as individual strains of the same species. B) classified as individual species of the same genus. C) split into different families. D) classified as the same species if they can mate via conjugation.
