changes in the gene pool can occur due to various mechanisms. in 1989, a large oil spill occurred in prince william sound, alaska, when the exxon valdez oil tanker ran aground. approximately 11 million gallons of oil were spilled and spread 1,300 miles along the alaskan coastline. the damage from the oil spill affected thousands of animals in the area, including killer whales, harbor seals, sea otters, fish, and sea birds. which mechanism most likely affected the gene pools of the organism populations in the areas around the oil spill?\no genetic drift\no gene flow\no gene mutation\no genetic variation

Answer

Answer:

genetic drift

Brief Explanation:

The oil - spill is a random, catastrophic event that likely caused a drastic reduction in the population size of affected organisms, which is characteristic of genetic drift. Genetic drift is the change in the frequency of an existing gene variant in a population due to random sampling of organisms. Gene flow involves the transfer of genes between populations, gene mutation is a change in the DNA sequence, and genetic variation is a general term for differences in DNA sequences among individuals. The oil - spill most likely caused genetic drift.
