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.
A knockout mouse (left) that is a model for obesity, compared with a normal mouse. There are several thousand different strains of knockout mice. Many mouse models are named after the gene that has been inactivated.n some instances, the gene may serve a different function in adults than in developing embryos. Knocking out a gene also may fail to produce an observable change in a mouse or may even produce different characteristics from those observed in humans in which the same gene is inactivated.
