Homology inference

This presentation shows how homologues are inferred from gene trees in the Ensembl database. Learn how to access these homologues.

Exercises 4

1. Get all the homologues for the human gene ENSG00000229314.
   
2. Count the number of “one2one” homologues between human and mouse.
   
3. Find the human orthologues of ENSMUSG00000004843 and ENSMUSG00000025746. For each homology, display the alignment and the dn value. Comment on the divergence.
