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 area where the droppings are deposited. An increase in predators, a volcanic eruption, and spraying a toxin are examples of factors affecting population size or survival, not gene - flow.

Answer:

bird droppings that contain seeds from a different location
