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.
Genomic data is used to make close comparisons between species and determine relatedness. Humans share about 99% of our genome with chimpanzees (98.7% with bonobos) and over 90% with the mouse.
