| Summary | 0006859: bootstrap values |
| Description | MEGA12 gives much higher bootstrap values than MEGA 11. I tested both versions with a data set of 600 nucleotides with two taxa (each five identical sequences) that differ in 1 nucleotide only. Bootstrapping with MEGA 11 gives a bootstrap value of 60-65%, MEGA 12 values of consistently 100%. With an alignment of 600 nucleotides (columns) the chances that one nucleotide (column) will be present in the resampled alignment with replacement equals
1 – [(x-1)expt(x)/(x)expt(x)]
= 63%
