Comparison of the pachytene FISH composite karyotype to various maize maps in standardized RMP units. The pachytene FISH composite karyotype is shown first in each panel, and the loci are connected by lines to their RN-predicted RMPs (a), their RMPs on the UMC 98 linkage maps (b), or their RMPs on the B73 genomic physical maps. The karyotypes are displayed as short arm-centromere-long arm with the centromere indicated by a yellow oval. The maize inbred line used in pachytene FISH for each locus is denoted by colored circles: B73 (green), Seneca 60 (red), and Mo17 (blue). Lines connecting loci on two maps differentiate between the different B73-derived chromosomes 1 (long-dashed), 4 (thick), 5 (short-dashed), and 8 (dotted) as well as the Seneca 60 (chromosome 3, red) and Mo17 (chromosome 6, blue) derived chromosomes
