Stabilizing Selection: intermediate traits rather than extreme traits are preferred
: intermediate traits show the highest survivability
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.
