Three maps of the region distal to R on N10. Mroczek 10 is from data presented here, Genetic 2005 10 is a consensus map that combines several genetic and RFLP maps, and IBM2 neighbors 10 is the most recently computed genetic map from a population of inbred lines (http://www.maizegdb.org). Actual genetic distances between loci (in centimorgans) are indicated below the Mroczek and Genetic 2005 maps. The position where N10 and Ab10 diverge (Rhoades 1942) is marked 2 cM from R on the Genetic 2005 map; most, if not all, of the 32 cM distal to this position are present on Ab10 in rearranged form. The isu163 locus was added to the IBM2 map on the basis of its tight linkage to rz569a on the CU 99 10 map. The three loci used for sample sequencing are indicated beneath the IBM2 neighbors 10 map (and marked with tree-like symbols). The maps have been normalized to the same length and include only those markers used in the Ab10-I mapping effort.
