  1. Significant results at p ≤ 0.05 are highlighted in bold, and those remaining significant after the Bonferroni correction for multiple tests are indicated with asterisks. N, number of sib-pairs; t, t statistic from the linkage regression; p, probability values. See text for variables abbreviations.
