Essay

Refer to the figure.
Figure 1
The figure shows data collected on a species of fish that lives on a coral reef. The fish were captured and studied three times-in 2000, 2005, and 2010. Four genotypes were found in an area of the coral reef (shown as A, B, C, and D). The figure shows: (1) the number of individuals of each genotype captured during each year, and (2) the percent of individuals infected with parasites captured during each year.
-Suppose this reef fish is found on several reefs. Each reef is largely isolated from the others. The parasite species is found on all of these reefs. The frequencies of fish genotypes vary across the different reefs and the parasites rapidly evolve to be able to circumvent the fish's parasite defense mechanisms. Under which conditions might the parasites be more effective at colonizing individuals from its home reef, and when would parasites be more successful at colonizing individuals from another reef?
