Significant associations are in bold and associations remaining significant after Bonferroni correction are underlined (Bonferroni-adjusted P-value = 0.0014). Least squares means with different superscripts had significant Tukey-Kramer contrasts. Genotype categories (1/1, 1/2, 2/2) relate to the alternate alleles designated in Table 1-2. n: number of samples with each rSNP genotypes.
