Hi

Is there any website or a reference book for the analysis of phylogeny tree that was designed to look for hiv-1 transmission dynamic in a population ?.

we have the tree using Maximum likelihood and maximum parsimony, separately, but not bale to analyze it as clustering looks strange with BT value in most our samples is very low (below 50 %) , in some cases giving 0 and 1 ( see attachment ).

So , kindly looking for an answer to how to analyze such trees
