Summary of DNA diversity indices.

Genetic profiles (GP), as delineated from observation of COI and Tpm diversities and grouping together different isolates (left part, top), draw outlines of five different scenarios in the demographic history of D. gallinae s. str and one of D. gallinae L1. Majority and 1–2 steps derived COI haplotypes represent a group of haplotypes whose frequency within a given isolate is >60% and which forms a less than 3-steps star-like genealogy. Results of tests for demographic expansion based on comparison of the observed distribution of pairwise nucleotide differences among haplotypes (mismatch distribution) to the distribution expected from a sudden-expansion model (Arlequin 3.11) are provided per isolate and per some groups of individuals (right part and bottom). Smaj refers the number of segregating sites detected in the majority and 1–2 steps derived COI haplotypes of the isolate under consideration, KT1 to the number of 1st-level Tpm Structure clusters, D to Tajima's D value, Majority COI to mitochondrial lineage which the majority COI haplotype belongs to, COI m.d. or Tpm m.d. to the profile of mismatch distribution in COI or Tpm dataset (notation: uni = unimodal; bi = bimodal; 2h = 2 haplotypes present only; 1h = a single haplotype present only), SSD to the sum of squared deviations (P[simulated SSD≥observed SSD]), r to the Harpending's raggedness index.
