Which of the following examples can cause gene flow between populations?

The right answer is Bird droppings that contain seeds from a different location .

In this case, a genetic diversity will occur between the plants of this different place and the plant that will chlorinate from the seed and grow (assuming that there are no plants similar to this region). Since their gametes will mix during reproduction, this will give new species thanks to the contribution of a new gene pool.

ya the other dude is right
