Comparing multiple species

Comparative genomics analyses performed by Ensembl allow you to directly compare included species across many chordate genomes. Ensembl constructs phylogenetic gene trees (or protein trees) to compare the gene models across species and infer homology relationships (Video 5).

Video 5 Comparing genes and species

Comparison of genomic sequence between species, whole genome alignments, protein families and synteny are available (Video 6). Whole genome alignments include sequence alignments between two species (‘pairwise alignments’), and multi-species alignments incorporating genomes of more than two species. Analysis of the pairwise alignments results in syntenic regions (i.e. where the sequence and gene order is conserved between two species).
