  1. Abbreviations: Gen. = genotype, P% = population percentage, CM = clinical mastitis, SCC = somatic cell count. * Numbers from tagged SNP +798 C > T in Table 2. 1No significance was detected between genotypes by Chi^2 odds ratio test. 2Mean ± 95% confidence interval given in column parentheses. 3P values analysed by ANOVA and Tukey's multiple comparisons, showing only results tested against the underlined (lower CM rate) genotype; - (dash) denotes no significance. 4Standard deviation from the mean given in column parentheses.
