Figure 2From: Evolutionary dynamics of a conserved sequence motif in the ribosomal genes of the ciliate ParameciumAverage K s , K a and K a /K s values (and standard errors) estimated for pairs of duplicated ribosomal genes (as products of the most recent polyploidization event in P. tetraurelia ). Average diversity values are examined between gene pairs where both copies contain the DUAYAWUW motif and gene pairs where at least one of the copies does not contain this motif.Back to article page
