The three genotypic classes are defined in Figure 1. Plants were grown in Citra, Florida, in the spring of 2004. Total seed numbers marked with asterisks designate significant differences at the 5% (*) or 1% (**) level from the cognate nontransgene control. The ratio is the seed number of each of the two transgene-containing genotypes divided by the seed number of the nontransgenic control. Weights of individual seeds are in grams. Averages and ratios of all events were calculated from all individual data. The population size was 269 ears and 92,213 kernels.
