A spotted population of fish in an isolated pond has a gene that controls spot color. The gene has two alleles, black (B) and red (R), and the alleles exhibit co-dominance. Scenario 1. The frequency of B is initially 0.5, and the population size in the pond is 20,000. A predatory fish is introduced to the pond. Experiments indicate that the predator uses visual cues to find its prey, and that it can more easily catch fish with red spots. What will happen to the following frequencies? (for each row, put an "X" in one of the 4 boxes) Increase Decrease Either Increase Stay the same or Decrease BB phenotype
