The mouse and human genome have large syntenic blocks of genes in common
Synteny between human chromosome 17 and mouse chromosome 11. Large conserved syntenic blocks 100 kb or greater in size are shown in human chromosome 17, mouse chromosome 11, and the inferred chromosome of their last common ancestor (reconstructed by analysis of other mammalian genomes). Direct blocks of synteny are shown in light purple; inverted blocks are shown in green. Chromosome sizes are indicated in megabases (Mb).
