Changes in the gene pool can appear due to manifold arrangements. In 1989, a great oil drop appearred in Prince William Sound, Alaska, when the Exxon Valdez oil tanker ran strained. Approximately 11 favorite gallons of oil were droped and publish 1,300 miles parallel the Alaskan coastline. The mischief from the oil drop artful thousands of animals in the area, including killer whales, encourage seals, sea otters, fish, and sea birds. Which arrangement most slight artful the gene pools of the organism populations in the areas environing the oil drop?
