About 99% of mouse genes have a homolog in the human genome, and for 80% of these genes, the best match in the human genome has, in turn, its best match against the orthologous mouse gene in the conserved syntenic interval.
Looking across the genomes of humans and mice, scientists have found that, in general, the systems that are used to control gene activity in both species have many similarities, along with crucial differences.
