SNP-phenotype associations were significant at a p < 0.009 level for some time span and location in each modality for at least one of the sexes in each of the four SNPs examined. SNP-phenotype-sex associations varied for the four SNPs in one or more of the following ways, as can be observed in Figures 4 and 5. The patterns displayed in the phenotype-genotype association trajectories described in this study were not predictable from previous studies of P3 related electrophysiology, but some are found in a number of other studies of development, which are discussed in the following sections.
