Genomicus is a genome browser that enables users to navigate in genomes in several dimensions: linearly along chromosome axes, transversaly across different species, and chronologicaly along evolutionary time.

Once a query gene has been entered, it is displayed in its genomic context in parallel to the genomic context of all its orthologous and paralogous copies in all the other sequenced metazoan genomes. Moreover, Genomicus stores and displays the predicted ancestral genome structure in all the ancestral species within the phylogenetic range of interest.

All the data on extant species displayed in this browser are from Ensembl.

Summary statistics of Genomicus version 110.01: (view species tree in pdf or newick)

Number of ancestral genes	4781173
Number of ancestral synteny blocks	80028

WARNING: Genomicus is based on data from Ensembl, and since the release of version 94, Ensembl has changed its phylogenetic trees reconstruction approach, causing large gene families (> ~400 homologs) to be split in several smaller families. Some paralogy relationships may therefore be lost.

To acces the most recent version of Genomicus without these paralogy issues, please use release Genomicus93.
