Genotypes identification by RFLP-PCR (on 2 % agarose gel): a before enzymatic digestion, single band, with 358 bp corresponding to “intact intron 4”, b post enzymatic digestion of PCR products, with the different genotypes (AA with 358 bp, AG with 358 bp + 208 bp + 150 bp and GG with 208 bp and 150 bp). M: molecular weight ladder (100 bp); pb: base pairs; PFLP-PCR: restriction fragment length polymorphism-Polymerase Chain Reaction
