Question 39 of 72 Bees pollinate red snapdragons in one part of the garden then fly over to another area and pollinate white snapdragons. After a few generations, the seeds from the white snapdragons start to produce pink snapdragons. Identify the mechanism that brought this change in gene frequencies. Genetic drift Gene flow Reproductive isolation Disruptive selection

This would be a gene flow!

The pink snapdragons, I assume, are an offspring of white and red snapdragons. There is a change in the genetic make up of the white dragons, which is influenced by the red snapdragons: so the gene flow was from the red snapdragons to the white ones!
