Paralog analyses reveal gene duplication events and genes under positive selection in Ixodes scapularis and other ixodid ticks

Table 1 Datasets used for the identification of duplicate genes (paralog pairs) in four species of ixodid ticks

Species	Number of ESTs	Number of TCs^a	Number of gene models^b
Ixodes scapularis	192,461	20,901	24,925
Rhipicephalus microplus	42,512	9403	NA
Rhipicephalus appendiculatus	19,123	2767	NA
Amblyomma variegatum	3992	478	NA

^aTentative consensus (TC) sequences were produced by separate alignment of expressed sequence tags (ESTs) for each species; ^bGene 2 models from the IscaW1.1 annotation; NA not available
