WebMar 31, 2024 · A role for disruptive selection in the emergence of different phenotypic forms and new species has been inferred in many systems (10, 11), but we still lack a clear understanding of the strength of selection needed to create such divergent discrete forms and details of the ecological factors causing the strength of divergent selection to vary. WebDisruptive selection occurs when heterozygous individuals are the least likely to survive. For that reason, this fitness pattern is also referred to as heterozygote disadvantage.
