The region shown in the Genome Browser window below lies at approximately (Unknown) cM on the ISU Integrated IBM 2009 genetic map for chromosome ?. This region (from to bp) represents cM.

Markers used to generate the map reported in Liu et al. 2009 were used to estimate cM per bp. The full map is also available at MaizeGDB. For this calculation, markers were ignored in regions where RefGen_v2 and the genetic map were not collinear. The full dataset used for this calculation is available here. Markers removed from the original Liu et al. dataset are available as a list here

Map positions reported are the centimorgan coordinate for the left side of the genome browser window shown below.

Regions at chromosome tips are reported as 0 cM. Regions smaller than 1 cM are reported as <1 cM. If the reported region is <1 cM, zoom out or check the "Segments of known genetic distance" track for more precise estimates.
