Comparison between hybridization contigs and FPC contigs. (Open bars) The hybridization contigs; (shaded bars) the FPC contigs. The horizontal lines indicate the positions of the genetic markers on chromosome 7 listed from top to bottom, excluding TEL13 and TEL14. RFLP markers are identified by numbers (see Fig. 4 for RFLP marker names—number is given in parentheses). Note that FPC contig anchored by RFLP markers 14 and 20 split under more stringent analysis conditions as indicated by the thick line. Arrows indicate merging of contigs under low-stringent analysis conditions.
