Abstract
Statistical calculations on sequence homologies provide evidence that the two phages Qβ and R17 have derived from a common precursor, although they are quite different in several properties. Moreover, duplications within the genom of each phage have occurred. These results are discussed with regard to the lack of translational repression between Qβ and MS2 phage group.
