Hybridization bands are those obtained by Southern hybridization of PstI-digested genomic DNA of each line with theCD probe. Proximal and distal refer to the proximal and distal breakpoint, respectively. Proximal breakpoint bands indicated in boldface include a 3.8-kb extra segment due to a polymorphism in aPstI site. Products of each PCR were digested with different restriction enzymes: B2-G6, BamHI–EcoRI; G5-D1, R1-C2, and A1-C1, DraI.
