Statistics on modern & ancestral genomes
Genomicus 03.01 contains 2440510 genes from 101 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 3018967 ancestral genes from 100 ancestral species, grouped into 71737 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).
