After moving to the mainland, what characteristic is unlikely to change in the island lizards’ descendants?
A A change in size
B A change in color
C A change in numbers
D A change in diet

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,
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.
