Question

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

Answer 1

The mechanism that brought a change in gene frequencies when bees pollinate red snapdragons in one part of the garden, then fly over to another area and pollinate while snapdragons which results in the production of pink snapdragons from white snapdragons is called GENE FLOW. Gene flow, also known as Gene Migration, is the transfer of genes from one population to another. 

Answer 2

Answer:

The correct answer is "Gene flow".

Explanation:

In this example, bees pollinating red and white snapdragons helped that white snapdragons started to produce pink snapdragons. The new trait found in white snapdragons indicates that the plants integrated the red snapdragons' genetic alleles responsible of color into its genome. This is a classic example of gene flow, the phenomena that describes the movement of gene alleles from one population to the other.
