Wow what a great theacher ... To explain this such a great way .. I Enjoy it alot !

[@nopainnogain.sylvere416]

Could you say a little bit the reason to use out-group in phylogenetic tree analysis? how to choose it? or any outgroup organism can be included to root the tree?

[@nazirahmed3715]

i actually can not interpret the phylogenetic tree because i dont know about distance matrix, neighbour joining method to explain but when i saw the lecture of your on youtube made me understand about the interpretation of phylogenetic tree. i want to send my tree can you plz interpret this for me, it is very urgent. i highly appreciate your lecture
thank you

Omg it's Professor Moriarty...

[@luckystarrani9703]

what is the unit of genetic distance?

[@marcobaneco3983]

hello I have to make a project with figtree and the teacher said that she wanted at least 95 of bootstrap puntuation in each label I have problems because I got 100 in someones but otherones are really low. Please help me I don´t know what I need to do to edit in seaview and get a higher puntuation
thx

[@mycobd1062]

Bootstrap (BS) values depends for each node or clade-how closely related each species/genus. You can't expect always over 95% BS in your molecular tree/backbone of this tree, it's a natural arrangement based on DNA analysis.

[@IkanPediaMalang]

Just delete the taxa that make the branch dont have 95%... If still can't delete your teacher..

sir could tell me how make bootsrap values

[@mycobd1062]

Bootstrap/posterior probability value comes automatically when you read your phylogenetic tree either open with treeview/figtree or dendroscrope software. In this study values come from MrBays analysis (posterior probability) so far.
