A DNA molecular weight marker is represented in the left lane (pGEM; Promega, Madison, WI). The remaining lanes represent the distribution of the three genotypes in F1 parents of the PiGMaP reference families. The AA genotype (600, 345, 180, and 75 bp) is observed in lanes 8 and 11 to the right of the molecular weight marker lane, and the BB genotype (600, 420, and 180) is seen in lane 13. Heterozygotes are in lanes 2, 3, 4, 5, 6, 7, 9, 10, 12, and 14 to the right of the molecular weight marker lane, and the genotype in lane 1 cannot be determined from this reaction.
