From: Divergent selection for natural antibodies in poultry in the presence of a major gene
Genetic trend for IgTotal, IgM and IgG natural antibody titers (expressed in genetic standard deviations) and in frequencies of the TLR1A C allele for the High (filled marker) and Low lines (open marker) with mass selection on IgTotal. The frequency of TLR1A C allele in the base population was based on imputed genotypes, as described by Berghof et al. [15]
