Fig. 2. Physical map of the bt locus. The top panel includes BAC clones
obtained from a 129/Sv-genomic library. The bottom panel includes BAC clones
obtained from a C57BL/6-genomic library. Black circles correspond to STSs
obtained from BAC ends and used to order clones in the contig. Broken lines
show the recombinant interval defined by the flanking markers 312Sp6 (an SSCP
found using BAC end sequences) and D15Mit272 (an SSLP). The three BAC clones
that were sequenced are shown with thick horizontal lines (RP23-24F24,
Accession Number AC084384; RP23-5K17, Accession Number AC084382; RP23-54K18,
Accession Number AC084385).
