Questions related to Phylogenetics
Though morphology of the true branched cyanobacteria is indeed tough and there do exist differences of opinions but as I can see, even the phylogenetic information is equally confusing, probably...

I have sequenced a vp1 partial gene of FMD virus and I have detected serotype O with sequence similarity of 95% to the closest on on blast search. I am struggling on how to determine the topotype...

There is a genus I focused, whose phylogenetic histories were obvious different based on chloroplast and nuclear loci. Both topologies were well support. In this case, maybe commonly, how to...

I want to draw a phylogenetics tree using a protein I am working with and its homologs using MEGA7. After the alignment using MUSCLE or CLUSTALW, there are so many options on the MEGA program for...

I am interested in constructing a phylogenetic tree on 30 viruses using their respective DNA polymerase sequences. The problem is that the sequences vary in length and are not as similar as one...

I’m familiar with strict and majority-rule consensus trees, as well as maximum clade credibility trees, as different ways of summarising results from phylogenetic inference. Recently, I have...

Normally dN/dS ratios are calculated and interpreted as below one negative selection, above 1 is positive selection and 1 means neutral selection. How to interpret dS/dN ratios? Programs like SNAP...

I have been out of the phylogenetics game for a while now (about 3.5 years) but I am needing to update a tree and want to make a good consensus tree. I am building a RAxML, PhyML, IQTree and...

hello, everyone,reciprocal monophyly often treat as a criterion of species delimitation, while it seems no differentiation to monophyly in phylogeny.

I was wondering what people’s thoughts on this topic were: how many SNPs per RAD locus should be used for phylogenetic studies? All agree this is important, with fewer SNPs per locus being...
