Question 2
2.
Scientists studied genetic variation in collared lemming populations that live in different locations. Scientists found that there was less genetic variation than expected between two of the lemming populations.
Which of the following most likely resulted in less genetic variation between these two populations?

Question 4
4.
When temperatures rise above freezing, snow melts which causes changes in the collared lemmings’ habitat.
Describe ways warming temperatures could cause the size of the collared lemming population to decrease.

Question 5
5.
Describe how fur color in the collared lemming population will likely change over time as temperature increases.
Explain using the principle of natural selection (be sure to state the original population, which fur color is best, why it is best, and what the end population will be)
