Fig. 3

Tp2-based sliding-window plot of Tajima’s D statistics (a) and nucleotide diversity (b) of T. parva sequences from the Great Lakes region. A window length of 100 nucleotides and a step size of 25 bp were used. The maximum nucleotide diversity and Tajima’s D values are observed between the nucleotide positions 200 and 300, containing the Tp2 epitopes 4 and 5. Abbreviation: Ep1-6, epitope1-6
