Three percent agarose gel electrophoresis of SmlI restriction enzyme products. Lane 1 contains a 50 bp DNA ladder; lanes 2–6 show the genotype (A/A) represented by two bands of 224 bp and 70 bp; lanes 7–10 show the (A/-) genotype represented by three bands of 294 bp, 224 bp, and 70 bp; and lane 11 shows the (-/-) genotype represented by one band of 294 bp
