Position of the 613 RosCOS on the TxE bin map. Thick black vertical lines represent the linkage groups indicated above the lines. The white boxes on the left of each linkage group symbolize the bins (minimum bin length). The number before the semicolon indicates the linkage group and the number following the semicolon indicates the genetic position (in cM) of the last marker within the respective bin. Numbers on the right of each linkage group represent the number of RosCOS that map to the bin.
