Statistics on modern & ancestral genomes
Genomicus 77.01 contains 1264176 genes from 69 extant species.
This data was analysed with a new method called AGORA (Algorithm for Gene Order Reconstruction in Ancestors; Muffato et al. in preparation) to identify 1112761 ancestral genes from 58 ancestral species, grouped into 33496 blocks of collinear genes.
The following tables present statistics on the data used in Genomicus, and on the reconstructed blocks in the ancestral species.
- For extant species, a "contig" means a segment of the genome sequence assembly (chromosomes, scaffolds, contig) with at least two genes.
- The average block length, the N25, N50 and N75 values do not take into account the singletons (blocks of one gene).
