A wolf population is living in an arctic climate. The wolf has a dominant trait for short fur and a recessive trait for long fur. Wolves with long fur are more likely to survive. Which of the following predictions is most likely?

A. The population of wolves will go extinct.

B. The percentage of wolves with long fur will increase.

C. The percentage of wolves with short hair will increase.

Explain why you chose your answer choice.

As the wolves with short hair decreases (because the environment does not encourage their survival), there will be less competition for the food that both would need. The long haired wolf even with a recessive gene, would increase in number.

A might be true but the hair length by itself will not cause the extinction of the entire wolf population.

C is simply not true. Your givens tell you that the long hair are more likely to survive.

B is the answer, for the reason given above.
