Dear Maria Habib

As I know there is no special phylogeny inference app implemented in XLStat.

I recommend starting with MEGA (https://www.megasoftware.net/) it is a free and easy to use phylogeny inference software with various possibilities.

As Csaba mentions, I believe there isn't any tool for this. However, if you want to analyze genetic data via Excel, I recommend you GenAlEx:

Another user-friendly tool that can parse with Excel look-alike genetic data is Genodive:

And here are some online tools specifically for phylogenetics:

If you want to perform multidimensional scaling or PCA based on genetic distance (calculated elsewhere, e.g. in MEGA or DnaSP ) then you can use XLSTAT. For phylogenetic tree construction, you can use MEGA.

Use MEGA for phylogenetic tree construction.
