Statistics on modern & ancestral genomes
Genomicus 01.01 contains 281605 genes from 12 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 219021 ancestral genes from 11 ancestral species, grouped into 9610 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).
