1. American bison was about to be extinct by the end of 19th century by the action of American Indian tribes due to large scale hunting. As a result, the numbers of bison declined rapidly due to the mass hunting and killing activities. When there is a rapid decline in the population due to various environmental events, the phenomenon is known as bottleneck phenomenon. Since the American bison was saved from extinction and restoration of population occurred in the 20th century, they are genetically much different from the wild ancestors. According to this the correct answers would be :
1. It has experienced a population bottleneck.
2. It is more genetically diverse.
Hence the answer is option option 4) - Both 1 and 2
2. Human migration is the process of movement of humans from one area to the other. Thus the correct answer will be:
Option 1: Your family moves to a new town in a different state.
