Solution
The answer is: "They are sterile."
Interspecies hybrids are usually not considered separate species because they are often sterile, meaning they cannot reproduce. This is due to the fact that the parent species have different numbers of chromosomes, which can cause problems during meiosis and result in nonviable or sterile offspring. This is known as hybrid sterility. Even if the hybrid is viable, it may still be sterile and unable to produce offspring. This prevents the hybrid population from becoming established as a separate species.
