Figure
3: Consistency of direct and indirect genetic effects on gene expression
across tissues and castes. Venn diagrams show significant (FDR < 0.1) differentially
expressed genes (DEGs) arising from pairwise comparisons representing
(A ) direct genetic effects and (B ) indirect genetic
effects in distinct tissues and castes. Generalized linear models were
used to assess the effects of (C ) supergene genotype
(SB/SB [BB] versus SB/Sb [Bb]; direct genetic
effect) and (D ) social environment (polygyne versus monogyne;
indirect genetic effect) among both tissues and castes, with
log2(expression ratio) and significance values generated
from these models shown in volcano plots. Between panels C and D is a
portion of panel C shown with significance scaled as in panel D.
