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.
Mice are, of course, in the first group 'animalia' or 'animals'. Then we have the 'phylum'. The phylum that mice fit into is 'Chordata', and we humans are also Chordata, and anything that has a backbone such as a fish, a crocodile, or a finch. Then we have the 'class'. The class of a mouse is 'mammal'.
