Why are mules male and female? How do they reproduce?

Mules were very common animals in the former countryside. When the production team still existed, our production team raised more than 20 mules. Later, with the popularization of agricultural mechanization, mules gradually withdrew from the historical stage as animal power. Even today, it is difficult to find mules.

Mules have thick heads, long ears and strong limbs. They look like horses and donkeys, so they are called "two differences". In fact, the origin of mules is "miserable". It is a "hybrid" of horse+donkey or donkey+horse.

The word "mule" about mule has a certain origin. According to historical records, the word "mule" was coined by ancestors based on their sympathy for the unfortunate life of mule.

Mules are the result of horse+donkey or donkey+horse "wild match". Therefore, in ancient times, some people with low quality often abused mules into "hybrids". Some high-quality people think that mules can't choose the origin of mules, but since they came into this world, they have made a lot of contributions to mankind. They are very hard and tired. So they added the word "tired" after the word "horse" and called these "two different" animals "mules" to remind people that mules always work for people. So it's called a mule.

In fact, there are differences between horses and donkeys, donkeys and horses. In general, mules born by mating between male and female donkeys are called mules, and mules born by mating between male and female donkeys are called mules. These two kinds of mules have their own characteristics and cannot be confused.

Generally speaking, "mule" looks like a horse, eats a lot, has great strength and endurance. At the same time, he is also very impatient. However, horses and mules are smarter and more understanding than donkeys. However, the service life of "Mules and Horses" is short, and generally it can only serve for about 20 years.

Mule looks a bit like a donkey. It has a small appetite and strong endurance, but its strength is small. But "mule" is not as clever as "mule", so it is difficult to understand the meaning of the owner. Besides, he has a stubborn temper. However, the service life of mule is very long, generally lasting about 30 years.

In general, people will buy "mules and horses" according to their own needs and economic conditions. The reason for distinguishing mules is to meet people's needs.

Mules are also animals, divided into male and female. However, due to the unpaired chromosomes of mule (63), the germ cells cannot divide normally. Therefore, male mules and most denominator mules are infertile. But because the mule's uterus can be pregnant, foreign scientists use special methods to get the mule pregnant and give birth. However, due to the complex technology and little practical significance, it has not been popularized. But through this experiment, people know that some female mules have certain fertility and just need technical assistance.
