Table 4 Evidence of selection on BLV total LTR in each genotype and subtype

From: Bovine leukemia virus long terminal repeat variability: identification of single nucleotide polymorphisms in regulatory sequences

  1. ȣ - indicates p-value where VR was significantly higher than VNR, positive selection; p-value not marked with an ou mean that VR was significantly lower than VNR, negative selection; p-value > 0.05 mean not significant difference between VNR and VR; the 68_G_P, 146_W_P and 297WS_M sequences were not classified to the subtypes giving 61 sequences to the subtype analysis
