Nucleotide diversity among SH3 -CNL members from C. canephora. Nucleotide diversity (Pi) is the average number of nucleotide differences per site between two sequences calculated by DnaSP v.5. Nucleotide diversity was calculated using the sliding window method where a window (segment of DNA) is moved along the sequences step by step. The parameter is calculated in each window, and the value is assigned to the nucleotide at the midpoint of the window. Both the default values were used: window length of 100 sites, and step size of 25 sites (midpoint). The alignment gaps were not counted in the window length (or slide).
