SciShow: Why Are Mules Sterile?

Teacher or professor: SciShow
Subject: Science
Content of the Lesson: Horse plus donkey — it seems like an unlikely combination. I mean, they're different species! And yet, when they get together, they can produce a mule or the lesser-known hinny. Either way, those offspring usually can't become parents themselves.
