Which of the following examples can cause gene flow between populations? an increase in predators to a population of zebra a volcanic eruption that kills half of a population of mice bird droppings that contain seeds from a different location a person that sprays a toxin on a group of mosquitoes

The right option is; bird droppings that contain seeds from a different location

Gene flow is the introduction or transfer of genetic variation from one population of a species to another, thereby influencing the general makeup of the gene pool (the population’s total genetic material) of the affected population. Bird droppings that contain seeds from a different location can cause gene flow between populations because the seeds in the bird droppings will introduce genetic material to another population of species hence, causing gene flow.
