No. of hit BAC clones19157 + 3316
Total no. of positive clones211177 + 3316

1Positive clones identified by PCR screening only.
2Hit BAC clones plus clones identified with the use of contig assembly data.
3Three of ten BAC clones providing the 220 and 226 bp products were missing from the assembly, thus their location in ctg285 could not be confirmed.
