I constructed a phylogenetic tree with MEGA 7.0 by using bootstrap (1000 replicates). But the final tree obtained lacked a scale bar, though it is there in the normal tree. What could be the possible explanation?
The bootstrap tree might be a consensus tree of 1000 bootstrap trees. Consensus trees do not have defined branch lengths in MEGA if I remember correctly.
But, I'm observing the other... I'm trying to add but, I'm failing... :(
