Figure 4: Allele-specific expression within the supergene. (A)
Volcano plot of allele-specific expression (ASE) for genes with
informative SNPs. Aqua dots represent significant instances (edgeR
glmQLFtest, FDR < 0.01), with the names of the genes showing
the most extreme ASE (|Log2FC|
> 3) indicated. (B) UpSet plot showing overlap between
genes with significant differential expression (DE, FDR <
0.01) in the SB/SB versus SB/Sb multifactorial-model
comparison and those with significant ASE in SB/Sb heterozygotes
(context for increased relative expression shown with arrows). Only
genes subjected to both types of analysis are included in this plot.
