Fig. 7: The likelihood of the population undergoing runaway selection decreases when there is a change in the genetic architecture.
From: Ecological disruptive selection acting on quantitative loci can drive sympatric speciation
Results are shown for data obtained when the strength of sexual selection is 5. The graphs show the proportion of cases where the population does not split, undergoes runaway selection, or a split when the loci controlling beak size do not show dominance and contribute equally to the trait (null), when they show dominance relationships (dom), when they contribute unequally (uneq), and when they contribute unequally and have dominance relationships governing them (uneqdom).
