Unlinked rRNA genes have differential frequencies across environments. We found that soils (13–41% unlinked) and sediments (7.7–29%) have more unlinked rRNA genes on average than anaerobic digesters (8.1–8.8%) and the human gut (0%). Results obtained from analyses of Moleculo and Nanopore metagenomic data are indicated with (m) and (n), respectively
