  1. The table lists the number of pairs belonging to the 3 categories obtained after tree topology comparison (+,+) (+,-) (−,-) for the variants of the datasets: 20p – MSA with maximum of 20% gapped columns. 20p25s – MSA containing a maximum of 20% gapped columns and a maximum of 25 sequences, 20p35s – MSA containing a maximum of 20% gapped columns and a maximum of 35 sequences. Statistically significant p-values are highlighted in bold.
