Question 19

Multiple Choice

Refer to the figure.
Refer to the figure.   Eurosta flies parasitize goldenrod plants, causing the plant to produce a gall in which the fly larva matures as it feeds on the plant. The larvae within the galls are parasitized by tiny wasps, which tend to parasitize the smallest galls, and are also fed on by Downy woodpeckers, which tend to feed on the largest galls. The figure shows the size distribution of galls before and after both wasps and woodpeckers have impacted their survival. This is an example of A)  allele fixation. B)  directional selection. C)  disruptive selection. D)  stabilizing selection. Eurosta flies parasitize goldenrod plants, causing the plant to produce a gall in which the fly larva matures as it feeds on the plant.
