- -; -/-: genomic sequence without Alu insert
- +; +/+: genomic sequence including Alu insert
- n.b.: no band
- FAP: result after amplification with flanking Alu primers
- Yellow boxes: amplification with internal Alu primer (IAP)
- CR: Combined result of both approaches for DO 3750
- Bold: complete result
- Red boxes: not further investigated (see Results/Discussion)
