The Sterile Mule

One of the most interesting things I've learned in high school was in my honors biology class. We were studying reproduction and the topic of hybrid species. Mules are an offspring of a horse and donkey. They are mostly used for trail riding and pulling carts. These rather ugly creatures can't reproduce. Many things in biology interested me but this unit was really appealing.
