Statistics on modern & ancestral genomes
Genomicus 59.01 contains
943946 genes from
53 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
771434 ancestral genes from
44 ancestral species, grouped into
31588 blocks of collinear genes.
The following tables present statistics on the data used in Genomicus, and on the reconstructed blocks in the
ancestral species.
note 1: For extant species, a "contig" means a segment of the genome sequence assembly (chromosomes, scaffolds, contig) with at least two genes.
note 2: The average block length, the N25, N50 and N75 values do not take into account the singletons (blocks of one gene).
