Mismatch distributions.

<p>The frequency distribution of nDNA polymorphisms within STRUCTURAMA-inferred populations calculated with the concatenated dataset in Arlequin. X-axes are in number of differences and Y-axes are in number of observations. Blue diamonds represent the observed data, green triangles and red squares represent upper and lower bounds expected under a model of expansion, respectively. P-values of the raggedness index for each analysis are given. A: Gulf-Atlantic. B: Suwannee. C: Carolinas. D: Everglades.
