DISTURB SELECTIONS;
DIRECTIONAL SELECTIONS, AND SITUATIONS SELECTIONS
DISTURB SELECTIONS, DIRECTIONAL SELECTIONS, AND STABLIZING SELECTIONS
DISTURB SELECTIONS, DIRECTIONAL SELECTIONS, AND BALANCING SELECTIONS

DISTURB SELECTION: NATURAL SELECTIONS THAT FAVOR BOTH EXTREMES PHENOTYPES AND AGAINST THE INTERMEDIATE.
WAY TO REMEBER: DISTURBING THE ECOSYSTEM.

Multiple Choice
MATCH THE GRAPH WITH THE TERM OF THE DEFINITION.
INDIVIDUALS WITH ALLELES FOR AN EXTREME TYPE ARE MORE LIKELY TO SURVIVE AND REPRODUCE.
THE SELECTION PRESSURE FAVORS THE EXTREME PHENOTYPES, DIVIDING THE POPULATION INTO 2 DISTINCT GROUPS.
INDIVIDUALS WITH INTERMIDIATE TRAITS ARE MORE LIKELY TO SURVIVE AND REPRODUCE
