Figure 2From: Integrating genome annotation and QTL position to identify candidate genes for productivity, architecture and water-use efficiency in Populus sppGlobal relationship between physical distance (in bp) and genetic distance (in cM) . The relationship is shown for both parental maps, P. deltoides map (circle), P. trichocarpa (triangles). Each point represents a physical and a genetic interval between 2 markers within a chromosome/linkage group.Back to article page
