Predictions for branch lengths of the ML tree using pairwise distances
| Conditions | Prediction |
| DBC ≥ DAB + DAC (incl. DBC = ∞) | dA = 0 |
| DAC ≥ DAB + DBC (incl. DAC = ∞) | dB = 0 |
| DAB ≥ DAC + DBC (incl. DAB = ∞) | dC = 0 |
| DAB = ∞ & DAC = ∞ | dA = ∞ |
| DAB = ∞ & DBC = ∞ | dB = ∞ |
| DAC = ∞ & DBC = ∞ | dC = ∞ |
| DAB = ∞ & DAC = ∞ & DBC = ∞ | At least two of the branch lengths are infinite |
