Dominance effects

  • The number of genes with significant overdominance, underdominance, and dominance. Dominance was tested against the null hypothesis OEms = OEMP, with genes at FDR ≤ 0.2 considered significant. For genes with significant dominance effects, the type of dominance was estimated by contrasting mean expression of the hybrid with each parent individually. Under- and overdominance are separated but complete and partial dominance are grouped together.
