Garfinas are a type of flowering plant. 

We are going to study four traits with respect to reproductive success:

• Flower petal colour - red or purple
• Thorns - present or absent
• Flower scent - ranges from fruity to rancid

Experiment 2:Some Garfinas have thorns and some do not. You collect data from wild Garfinas populations and discover that plants with thorns have significantly less damage from herbivores (predators) then plants without thorns. Herbivore damage may require plants to put energy into repairing themselves that otherwise could go towards reproduction. Herbivores can also damage the reproductive structures of the plant or kill the plant. 

You decide to use seed production as a measurement of reproductive success. By counting the number of seeds and comparing it to the amount of herbivore damage you show that, as predicted, larger amounts of herbivore damage equal lower reproductive success, and smaller amounts of herbivore damage equals higher reproductive success.

What is occurring for the thorn phenotype in Garfinas plants?

Select one:

a. Disruptive selection

b. You can't tell unless you know what genotype codes for each phenotype, or what alleles each plant has. 

c. Genetic drift

d. Recessive selection

e. Directional selection
