Fig. 5: Sexual selection does not play a role in dictating the evolutionary trajectory of the population.
From: Ecological disruptive selection acting on quantitative loci can drive sympatric speciation
In this modeling setting, sexual selection acts on two secondary sexual characters—choosiness of the females, and ornament size of the males. The figure describes the results obtained when the strength of disruptive selection is ~3.85. a The proportion of cases where the population undergoes a split, runaway selection, or does not split remains the same with increase in the magnitude of strength of sexual selection at play. b The intensity of split, whenever it occurs, also does not change with change in the strength of sexual selection. The error bars indicate means ± standard deviations.
