Sliding window analysis of nucleotide diversity in the ITS and flanking 18S and 16S rDNA regions of <i>N. bombycis</i> (Part A), <i>N. granulosis</i> (Part B) and <i>V. cheracis</i> (Part C).

<p>A sliding window of 50 base pairs is used, with an increment of 25 base pairs. Nucleotide diversity is calculated as the average heterozygosity per site (<i>π</i>) and the average number of nucleotide differences per site (<i>θ_W</i>). Error bars show the standard error for each window.
