How does reducing gene flow cause speciation?
O
A. It allows divergence to occur.
O
B. It eliminates fixed alleles.
O
C. It increases gene flow.
O
D. It stops adaptive radiation.

Reduction of gene flow causes speciation because the populations with reduced gene flow both begin to evolve independently.
