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.
