Upcoming Ensembl Platform Transition

This is the final release of its kind on this website.

In summer 2026, this site will bring you to the new Ensembl platform currently at beta.ensembl.org.

Human vs Great Tit LastZ results

Human (Homo sapiens, GRCh38) and Great Tit (Parus major, Parus_major1.1) were aligned using the LastZ alignment algorithm (LastZ) in Ensembl release 96. Human was used as the reference species. After running LastZ, the raw LastZ alignment blocks were chained according to their location in both genomes. During the final netting process, the best sub-chain was chosen in each region on the reference species.
