p-distances (p-D) and standard error (SE) values of mitochondrial H-orfs and cox1 in hermaphroditic freshwater mussels
| Species | Gene (N) | Nucleotide | Amino acid | p | ||
|---|---|---|---|---|---|---|
| p-D | SE | p-D | SE | |||
| Utterbackia imbecillis | H-orf (7) | 0.070 | 0.008 | 0.181 | 0.022 | 1.000 |

| Margaritifera falcata | H-orf (4) | 0.003 | 0.002 | 0.004 | 0.004 | 1.000 |
| cox1 (2) | 0.000 | 0.000 | 0.000 | 0.000 | 1.000 | |
| Lasmigona compressa | H-orf (2) | 0.029 | 0.007 | 0.065 | 0.017 | 1.000 |
| cox1 (2) | 0.000 | 0.000 | 0.000 | 0.000 | 1.000 | |
| Lasmigona subviridis | H-orf (2) | 0.016 | 0.005 | 0.021 | 0.010 | 1.000 |
Note: N number of sequences used. Multiple cox1 sequences were not available for L. subviridis. The probability of rejecting the null hypothesis of strict-neutrality (d N = d S) in favor of the alternative hypothesis (d N > d S) (in the p column) is shown. d S and d N are the numbers of synonymous and nonsynonymous substitutions per site, respectively
