Which of the following is an example of gene flow?
A)Pollen from a population A plant lands on the same plant (mating with itself).
B)Pollen from a population A plant lands on another population A plant.
C)Pollen from a population A plant lands on a population B plant.
D)Pollen from a population B plant lands on a population B plant.

Question

Quizplus · Accepted Answer

Gene flow occurs when alleles or genes are exchanged between populations. In this case, pollen from one population (A) is landing on another population (B), resulting in potential gene flow between the two populations. Option A is not an example of gene flow as mating with oneself does not result in genetic exchange with other populations. Option B does not involve gene flow between populations, as it only involves gene exchange within the same population. Option D also does not involve gene flow between populations, as it only involves gene exchange within population B.
