The correspondence between physical location and maps constructed using different mapping methods. (a) Correspondence between the genetic map and physical location. (b) Correspondence between radiation hybrid maps versus physical location. The GB4 (black) radiation hybrid map shows a jump at the centromere, reflecting a sequencing gap and possible increased radiation sensitivity in the region. The jump for the Stanford G3 map (blue) is not easily estimated and is suppressed in the published map. Chromosome 1 is shown here for illustration, and the corresponding figures and data points for the entire genome are available in the additional data files.
