Figure 1.

Sex-average genetic linkage map of the prairie vole. Linkage groups labeled with a number or X could be assigned to that specific prairie vole chromosome. Linkage groups that could not be assigned to a chromosome are labeled as LG#. The scale on the left refers to centiMorgans (cM). Markers are color coded with respect to the orthologous mouse chromosome (see color key). Markers with a name that begin with FI and are followed by 6-digit number are BAC-end sequences. Markers colored in black (NA) do not share an orthologous position in the mouse genome. All other markers are labeled by gene name.
