phylogenetic tree - (Nov/01/2009 )

Hi all

I'm currently writing a review about a family of genes and I want to make a phylogenetic tree. The thing is that I do not know what software to use. I've used DNAstar end Geneious but they give me different trees. When I look in other reviews I often see phylogenetic trees that are supposed to be similar, but are completely different. Is there a golden standard on how to make a ph. tree?

Thanks

There are different algorithms used for phylogenetic trees. Commonly used are e.g. maximum parsimony, neighbour joining, baysanian analyses.....and the programm used depens on the algorithm. A good overview on the different methods is given e.g. in book "Reading the story in DNA".
