Biology Stack Exchange is a question and answer site for biology researchers, academics, and students. It's 100% free, no registration required.

So I have a project student (undergraduate) who has been assigned a project to study the evolution of a gene (and possibly related genes) through species. I am not an evolutionary biologist, and hence am not too experienced in the workflow usually followed in studying the evolution of a gene in molecular phylogenetics. I have a brief idea, but may be wrong, and hence please do correct me.

The first aim is obviously sequence data collection for the requisite gene (and a few for a good outgroup), plot them in a phylogenetic tree, and analyse the distances, Ka and Ks ratio.

The next logical thing in my mind was a simple data collection for SNP analysis, and see if the SNP's are conserved, across species, and possibly if they impact protein structure.

But that's where i draw a blank. Any other ideas?

Uh naw snps shouldn't be first; snps are later –  caseyr547 Jul 28 at 23:58
    
First should be clustering homologous Regions with clustalx and the like then measuring the distance between major regions....regions can be identified with hmm software like the nncbi conserved domain software –  caseyr547 Jul 28 at 23:59
    
Read my friend Matt olsons ttu. papers his evolutionary work should provide a good guide –  caseyr547 Jul 29 at 0:05
    
The snp idea is fine but it does betray your work in Molecular as that was my first suggestion to Matt –  caseyr547 Jul 29 at 0:06
