Deleterious mutations destabilize ribosomal RNA in endosymbiotic bacteria

In populations that are small and asexual, mutations with slight negative effects on fitness will drift to fixation more often than in large or sexual populations in which they will be eliminated by selection. If such mutations occur in substantial numbers, the combined effects of long-term asexuali...
