Chromosome 2 from the new NCCCWA linkage map is shown as an example. Annotation of genes linked to the marker or BAC contig from the 1st generation physical map are connected to the marker name by underscore (e.g. OMM3080_TAP1_ctg260). Annotation of "or_?" means that the marker is duplicated and only one of two BAC contig was identified for the marker. Blue, Green, Red, Black and Italicized font markers were mapped to their specific location on the linkage group at LOD scores of 4, 3, 2, 1 and 0, respectively. Sex average distances between markers are shown in cM.
