This track shows syntenous (corresponding) regions between human and mouse chromosomes. It was created by looking for homology to known mouse genes in the draft assembly.
See http://www-genome.wi.mit.edu/mouse/synteny/index.html for more information about the data and methodology. Additional human-mouse synteny maps are available at http://www.ncbi.nlm.nih.gov/Homology/ .
The data for this track was kindly provided by Michael Kamal at the Whitehead Institute.
