Verified Answer :

A group of students are walking in the park, and one of them takes a picture of a pollen grain that is being blown by the wind. Gene flow at work would be the best caption for the picture.

Answer:

The most appropriate answer would be b. gene flow at work.

Transfer of pollen grain forms the example of vertical gene transfer that is, transfer of a gene from parent to the offspring.

A pollen grain is the male gamete of the parent plant. It contains the genetic material or information of the plant.  

It is pollinated or transferred to the stigma of the plant of same species with the help of air, water, bees et cetera. Successful pollination results in the formation of the zygote.

Thus, gene or genetic material is transferred from parent plant to the offspring. Hence, the student can use "gene flow at work" as the caption of the picture.
