  5. Verification analysis • Single colony picking Identity confirmation • Digestion with restriction enzymes • BAC-end sequencing • Marker association - PCR markers development • Amplicon sequencing and sequence alignment • Localization • IL lines mapping confirmation. - FISH mapping.

  6. Restriction enzyme digestion and BAC end sequencing • SP6 and T7 end sequences alignament and comparison with SGNdatabase Fingerprinting analysis with the restriction enzyme BamHI
