EnsemblCompara Get Orthologues

Find orthologous genes (genes in different species that evolved from a common ancestor) using Ensembl Compara. Essential for comparative genomics - finding the mouse, zebrafish, or fly equivalent of a human gene. Returns orthologue gene IDs, species, homology type (one-to-one, one-to-many), and taxonomy level of divergence. Example: TP53 in human has a one-to-one orthologue (Trp53) in mouse.
