Imagine that you are the lead scientist studying whether or not a change in island lizard population would be evidence for gene flow. What is the most appropriate hypothesis for this experiment in terms of the results you would expect? After a gene flow event,

OPTIONS

A: if the diversity of the lizards changes, then many generations will have passed.

B:if many generations of lizards are able to interbreed, then the size of the lizards will change.

C:if the diversity of the lizards changes, then the color of the lizards will change.

D: if the size of the lizards changes, then there would have been a gene flow event over time.
