Numbers in parenthesis are the standard errors

Bold characters highlight significant $h^{2}$ , $r$ and breed effects

Range shows the 5th quantile and 95th quantile, respectively

The natural antibodies are coded as follows: MDP Muramyl dipeptide, KLH Keyhole limpet hemocyanin, IgA Immunoglobulin A, IgG Immunoglobulin G, IgM Immunoglobulin M

N number of analyzed samples

^aBreed effects are relative to Swedish Red (SRB)

^bVariance components and effects were estimated using a square root transformation
