Basics of Phylogenetics - How UPGMA and Neighbor Joining trees are generated?

[@fatimanasir5347]

Dear sir, how can we calculate distance matrix from Alignment score matrix

[@shivi3132]

Thank you so much for this. What to do if distance between more than 2 species is same eg if the distance Between D and E and A and B was 10 in first step??

how to prove that the parent node always lie above its child node in upgma algo ?

[@suvajitsaha1073]

To study closely related gene sequences of a similar species which method will be best suitable. If it is distance based method then which one? UPGMA or NJ? Plz advice.
