It is rumored that it is not an auspicious thing for a mule to get pregnant, why do mules die when t

I don't know if you've ever heard of the saying that it is very unlucky for a mule to get pregnant, and it must die after pregnancy. This is because mules are not infertile, and even after pregnancy, they cannot fully give birth to the baby in their womb. The chromosomes of the mule are located between the horse and the donkey, the horse has 64, the donkey has 62, and the mule has 63, this number is a singular number, so the chromosomes cannot be sorted normally during mating, so there is no way to have children normally.

Although mules are divided into male and female, female mules will also have a normal reproductive system, but their genes are in a defective state, and even if they are pregnant, there is still no way to give birth to a baby mule. In addition, the chance of pregnancy of a female mule is very small, and naturally there will be no corresponding small animals. Even if the mother mule is pregnant, there is no way for the pelvis to expand, so it is very difficult for the fetus to be completely born, and even in the process of childbirth, because the pelvis is small, there is a phenomenon of one corpse and two lives.

Mules are a very common animal, but many farmers compare mules with horses and donkeys. But the pregnancy of a mule is an accidental event, and everyone does not know about it, and some people even think that it is impossible for a mother mule to get pregnant at all, which is a wrong perception. Some people will panic when they learn that the mother mule is pregnant, so in order to protect the life of the mule, they will find a veterinarian to abort the mother mule, so there is such a saying, but this is not a 100% chance.

It is important to know that each species has its own rules of survival, so whether or not a healthy animal can be born depends on the species. In addition, chromosomes also determine whether the animal has the corresponding fertility? After all, chromosomes are in an odd number, and no matter how much they do, it is impossible to complete the whole process of conception.

Therefore, if you want to extend the life of the mule, you must control the various behaviors of the mule, do not have the phenomenon of mating, and do not let the mule do heavy work, which can easily exhaust the mule's body.

Because the pelvic bones of mules cannot be opened and closed, they are prone to dystocia, and there is a problem of reproductive isolation.

This is because of the species, but there is no scientific basis for the claim that a mule dies when pregnant.

Because the mule is originally crossbred, the chromosomes in its body are singular, and the chromosomes of the biological organisms born during pregnancy are asymmetrical, and there is no way to survive.

Because mules are the offspring of horses and donkeys, one is tetraploid and the other is diploid, and the mule is triploid when it is born, when fertilization, the synchromosome will be disordered, so it cannot form an embryo.

Mules can be divided into horse mules and donkey mules, when the male donkey can mate with the mare, give birth to a mule "horse mule", if it is a male horse and a female donkey mating, give birth to a "donkey mule", "horse mule" is large, with the weight bearing capacity and resistance of a donkey, with the flexibility and running ability of a horse, is a very good draft animal, but can not be born. "Donkey mules" are small and generally not as good as horse mules, but sometimes they are fertile.

Mules are pregnant and die, because the pelvis of the mule is not able to grow during pregnancy.

The chromosomes of the mules are different, which leads to some physiological defects in their physiology. The pelvis of a mother mule cannot grow during pregnancy, which means that even if the fetus is developed, it will not be born smoothly.

The total number of chromosomes in the mule is the difference between the odd and the sun, and when the horse and the donkey cross to form the fetal skin, the chromosomes cannot be sorted normally, and healthy reproductive cells cannot be formed in the mule's body, so the mule Kai brother has no way to give birth normally.

Of course, you can't get pregnant. Because the snail is obtained by breeding with horses and donkeys, it is like a new species of wax. So there will be some inherent flaws in the oak bush. You can get pregnant without Sakura.

Mules cannot get pregnant; Because the mule is a cross between a horse and a donkey, and is not capable of reproduction, his parents are reproductively isolated.

1. Because mules are the offspring of horses and donkeys, one is tetraploid and the other is diploid, and the mule is triploid when it is born, when fertilization, the chromosomes will be disordered, so it cannot form an embryo. 2. Mule Kekela is divided into horse mule and donkey mule, when the male donkey can mate with the mare, give birth to a mule "horse mule", if it is a male horse and a female donkey mate, give birth to a "donkey mule", "horse mule" is big, with the weight bearing capacity and resistance of a donkey, with the flexibility and running ability of a horse, it is a very good draft animal, but the hail can not give birth. "Donkey mules" are small and generally not as good as horse mules, but sometimes they are fertile.
