Statistics on modern & ancestral genomes
Genomicus 56.02 gathers
888217 genes of
53 extant species.
From this data,
782121 ancestral genes from
44 ancestral species are defined and grouped into
59444 synteny blocks.
Here are some statistics about the genome data of the species used in Genomicus, and the reconstructed blocks of the
ancestral species.
For extant species, a «contig» means a chromosome-like structure (chromosomes, scaffolds ...) with at least two genes
