Figure 3.—

Graphs comparing the observed marker locations by FISH with those predicted from the genetic map (A) and those predicted from the RN–cM map (B). The locations of pericentric heterochromatin and the centromere are indicated by darker bars and a circle, respectively, along the x- and y-axes of each graph. The rectangle in each graph indicates the physical location of pericentric heterochromatin. The TG378 marker is indicated by a triangle and was not included in the regression analyses because it was mapped to the wrong arm. Regression equations are (A) y = 0.792x + 1.35, r² = 0.849; (B) y = 0.931x + 0.29, r² = 0.978.
