All QTL located in this study.

1Chromosome: the chromosome each QTL is located on.2Trait: each trait is shown as follows: total IgG or IgG isotype response, followed by the week relative to vaccination.3cM: the QTL position on the chromosome (centiMorgans).4F: the F-statistic of each QTL, all are at least 5% chromosome wide, * 1% Chromosome wide and ** 5% Genome wide.5“a” and “d” are the additive and dominance effects of each QTL, * = p6Var%: the additive phenotypic variance explained by the QTL.7The 95% confidence intervals of each QTL (centiMorgans).
