Horizontal gene transfer and diverse functional constrains within a common replication-partitioning system in Alphaproteobacteria: the repABC operon

Table 2 Average between-locus distance for the different loci

Locus	Average distance+	P. Invariant sites	Shape parameter α
*repA*	0.72530	0.194	1.176
*repB*	1.13479	0.089	1.661
Intergenic region	0.45827	0.0	0.47

The average distance over all possible sequence pairs for each locus, along with the specifications made by jModelTest regarding the substitution model.
+Average distance over all possible pairs of sequences.
All the loci but the "Intergenic region" selected the GTR model with correction for across site rate variation and invariant sites (GTR+I+G). The "Intergenic region" selected *TPM2 with correction for across site rate variation (TPM2+G).
*This model implies AC = AT; CG = GT; AG = CT;
