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

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

Answer

Brief Explanations:

Gene flow is the transfer of genetic material from one population to another. Bird droppings with seeds from a different location can introduce new genes to a plant - population in the new area, thus causing gene flow. An increase in predators, a volcanic eruption, and spraying a toxin are examples of factors affecting population size through natural selection or mortality, not gene flow.

Answer:

bird droppings that contain seeds from a different location
