Question

When living together, horses and donkeys can mate. When this occurs, they typically produce sterile (unable to reproduce) hybrid offspring called mules. This is commonly used as an example of a reproductive barrier between closely related species. Suppose that in a large population of horses, there are a few that carry a version of a gene involved in scent reception that causes them to be strongly repelled by the smell of donkeys. In an environment where donkeys are present, do you expect the frequency of this allele to increase, decrease, or stay the same in the horse population over many generations? Thoroughly explain your reasoning
