Fig. 3From: Genetic diversity of Bovine Viral Diarrhea Virus from cattle in Chile between 2003 and 2007SDT matrix of pairwise identity scores generated by alignment of a 420 bp fragment of the E2 gene for 37 BVDV viruses. Each colored cell represents the percentage of identity between two nucleotide sequences, one horizontally and the other vertically, that intersect in the cell. A figure indicating the correspondence between pairwise identities and the colors is includedBack to article page
