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.

Answer

Brief Explanations:

Selective pressure from fishing nets that target large - sized cod leads to a reduction in the population of large - cod individuals. This selective removal of certain phenotypes reduces the overall genetic variation in the population as genes associated with the large - size trait are being removed at a higher rate. Gene flow is not indicated in the problem as there is no mention of movement of individuals or genes between populations.

Answer:

The genetic variation in the population is decreasing due to selective pressure.
