The recombination rate track represents calculated sex-averaged rates of recombination based on either the Whitehead Institute (WI) or MGD genetic maps. By default, the WI genetic map rates are displayed. Female and male specific recombination rates are not available for these maps.
The WI Mouse Genetic Map is based on 6,336 genetic markers with a total of 92 meiotic events. For more information on this map, see W.F. Dietrich et. al., "A comprehensive genetic map of the mouse genome.", Nature, 380(6570), pages 149-152 (1996).
The MGD Genetic Map was created at the Jackson Laboratory.
Data for these maps was downloaded from the NCBI ftp site.
Each base is assigned the recombination rate calculated by assuming a linear genetic distance across the immediately flanking genetic markers. The recombination rate assigned to each 1 Mb window is the average recombination rate of the bases contained within the window.
To view a particular map, select the corresponding option from the "Map Distances" pulldown list. By default, the browser displays the WI genetic map sex-averaged distances.
This track is produced at UCSC and uses data that are freely available for the WI and MGD genetic maps (see above links). Thanks to all who have played a part in the creation of these maps.
