Table 2 Mean pairwise genetic distance between the Rhipicephalus spp. analysed for the calreticulin gene sequences. Ticks are encoded as in Table 1. Mean p-distances (below the diagonal) have been estimated as implemented in the MEGA 7.0 software. Only sequences with intron region were used. Standard error estimates are shown above the diagonal and were obtained by a bootstrap procedure (1,000 replicates)

From: Exon-intron structure and sequence variation of the calreticulin gene among Rhipicephalus sanguineus group ticks
