Summary of the significant results of the global and extended MK tests indicating purifying selection in Camelus mitogenomes.
| Selection test | mtDNA gene | NI (P) | |
|---|---|---|---|
| dromedary vs. domestic Bactrian camel | g-MKT | PC genes | 2 (0.006**) |
| e-MKT | ND6 | 13.33 (0.009**) | |
| dromedary vs. wild Bactrian camel | e-MKT | ND6 | 14.66 (0.007**) |
| domestic Bactrian camel vs. dromedary | e-MKT | PC genes | 3.47 (0.001**) |
| domestic vs. wild Bactrian camel | e-MKT | PC genes | 2.17 (0.035*) |
| domestic vs. wild Bactrian camel | e-MKT | PC genes | 2.97 (0.008**) |
| one- vs. two-humped camels | g-MKT | PC genes | 1.48 (0.041*) |
The two-tailed P-values of Fisher’s exact tests are shown. P-values with asterisk are significant with the following significant levels *P < 0.05; **P < 0.01. PC = concatenated protein coding genes, g-MKT = global MKT, e-MKT = extended MKT, NI = neutrality index.
