Concept

Problem: How do stabilizing and disruptive selection differ?a) With stabilizing selection, the phenotype for a trait does not influence survival. With disruptive selection, the phenotype for a trait affects survival.b) Stabilizing selection reduces the amount of variation in a trait. Disruptive selection increases the amount of variation in a trait.c) With stabilizing selection, extreme individuals have high biological fitness. With disruptive selection, extreme individuals have low biological fitness.d) Stabilizing selection produces adaptation. Disruptive selection is nonadaptive.
