The correct answer is: E.No gene flow.

Explanation:

Gene flow refers to the transfer of alleles or genetic material between different populations, often through migration or dispersal of individuals (or pollen in this case). If wind carries pollen from one population to another, it introduces new genetic material into the second population, violating the assumption of no gene flow in Hardy-Weinberg equilibrium.

The other options are incorrect because:

A.No genetic drift (bottleneck effect): This refers to random changes in ...
