Part A:
Which process is responsible for changing the frequency of alleles observed in the medium ground finch population?
A 
natural selection
B 
selective breeding
C 
genetic equilibrium
D 
convergent evolution
Part B:
Which BEST describes how the process identified in Part A changed the frequency of alleles?
A 
Finches with mutations were unable to survive to reproductive age and did not produce offspring.
B 
Finches that mated with individuals with desired traits were better able to survive to reproductive age.
C 
Finches that were able to change their genotype to match the environment were most likely to survive.
D 
Finches with traits better suited for survival were able to reproduce and pass these traits to their offspring.
