A scientist works near a lab mouse in Rome in this February 7, 2001 file photograph. Scientists have mapped 98 percent of the genome of the mouse in a breakthrough that is expected to speed up the hunt for human genes and improve understanding of how they contribute to diseases. A consortium of scientists from Britain, Canada and the United States collaborated on the genetic map - regarded as the most important since the human genome was sequenced - which was published August 4, 2002, on the website of the science journal Nature.
