Questions: As the human population grows and countries continue to develop, the demand for large fish has been steadily increasing. Unfortunately, the average size of the cod has decreased because the fishing nets were designed to catch the large fish and the smaller individuals could escape more easily. What is most likely happening to the genetic variation of the population of North East Arctic Cod? The genetic variation in the population is increasing due to selective pressure. The genetic variation in the population is decreasing due to selective pressure. The genetic variation in the population is increasing due to gene flow. The genetic variation in the population is decreasing due to gene flow. Mark this and return Save and Exit Next Submit

Solution

Solution Steps

Step 1: Analyze the scenario

The passage states that larger cod are being caught, while smaller cod escape. This means the smaller cod are more likely to survive and reproduce, passing on their genes for smaller size.

Step 2: Consider the impact on genetic variation

Since larger cod are being removed from the population, the genes for larger size are becoming less common. This reduces the overall genetic diversity within the cod population.
