According to who?
Long Story Short
The short answer is that mules have chromosomes that do not match up, so they cannot make sperms or eggs. Thus, they are sterile and cannot produce offspring.
Looking Closer
More specifically, a mule has 32 horse chromosomes and 31 donkey chromosomes. A total of 63 chromosomes. Normally, an organism would have two copies of one chromosome, one from the mother and the other from the father. However, for mules, they will get two different sets of chromosomes since the mother is a horse, and the father is a donkey. These genes will not exactly be matched sets, but they are still relatively similar (enough to produce the mule offspring in the first place). To reproduce, a process called meiosis will happen, in order to get one copy of each chromosome into the sperm or egg. During this process, the chromosomes will need to “match up” to another. Unfortunately, the donkey and horse chromosome are not similar enough to pair. Additionally, the mule will also have an extra unmatched horse chromosome, so sperm or eggs are unable to be made.
