Figure 2. — Grouping of adult hens and their hatchlings on the basis of IgM and IgG antibody titers to 5 antigens: KLH, PC-BSA, PC-OVA, dsDNA, and OVA. Ordination plots by principal component analysis. Diagrams include 14 to 15 birds (hens and hatchlings) from each line (enveloped) that were analyzed with ELISA. ‘Eigen values’ explaining the amount of variation were 73% horizontal and 18% vertical. Diagram includes antigen and isotype combinations. Length and direction of arrows indicate the contribution of the antigen-isotype combination to the grouping of the lines. Small fonts after the antigen label represent the isotype m: IgM and g: IgG.
