Cow vs Hybrid - Bos Indicus LastZ results

Cow (Bos taurus, ARS-UCD1.3) and Hybrid - Bos Indicus (Bos indicus x Bos taurus, UOA_Brahman_1) were aligned using the LastZ alignment algorithm (LastZ) in Ensembl release 111. Cow 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.
