Indication of relationship between genetic distance and physical distance for the ten Brassica A genome chromosomes. Genetic distance (cM) is derived from the B. napus BnaWAIT map. physical distance (Mb) is derived from concatenated scaffolds of B. rapa Chiifu-401. The orientation of the genetic map for each LG is consistent with that of Parkin et al. . Each marker represents a unique alignment of sequence for a marker within the genetic map against the corresponding sequence scaffold.
