Estimated genetic correlations, and phenotypic correlations of KLH-binding natural antibody (NAb) titers and total antibody concentrations (μg/ml) in an adolescent White Leghorn chicken population.
| Genetic correlation | Phenotypic correlation | |
|---|---|---|
| IgMa/tIgM | 0.91 (0.06) | 0.41 (0.02) |
| IgA/tIgA | 0.38 (0.22) | 0.26 (0.03) |
| IgG/tIgG | −0.61 (0.55) | 0.08 (0.03) |
| IgT/tIgTb | −0.27 (0.31) | 0.03 (0.03) |
The correlations between: KLH-binding IgM NAb (IgM) titer and total IgM (tIgM) concentration; KLH-binding IgA NAb (IgA) titer and total IgA (tIgA) concentration; KLH-binding IgG NAb (IgG) titer and total IgG (tIgG) concentration; and total KLH-binding NAb (IgT) titer and total antibody (tIgT) concentration. tIgM, tIgA, tIgG, and tIgT were log10-tranformed for the analyses. SE is shown in parentheses.
aDam component was fixed at boundary (0) in ASReml analysis.
btIgT = tIgM + tIgA + tIgG.
