Chapter 1416 (1/2)

The Jiuli nationality followed the Chiyou tribe and lived here for thousands of years.

For thousands of years, the population has ranged from thousands to tens of thousands, or even hundreds of thousands. However, their tribe has always been married by close relatives.

In fact, these people do not know what close relatives are.

For example, in ancient times, many, even many princes and nobles married their cousins in this way, which naturally gave birth to many premature deaths, even idiots.

Now the same is true of the Jiuli tribe. Except for the marriage of internal close relatives, there is no marriage of those outside.

Over time, the tribal population has become smaller and smaller.

The tribal chief and elders don't know what the situation is, and the tribal witch doctors and wizards don't know either.

However, more and more people in the tribe are getting sick, which is still strange, which makes Mao and the patriarch pay attention.

This time, I learned that Xiao Chen came and specially asked Xiao Chen to see it.

”Next of kin marriage?” Mao asked the patriarch strangely.

The so-called close relatives refer to the common blood relationship among three generations or within three generations. If they intermarry, it is called consanguineous marriage. Both of them have too many similar genetic factors, and their offspring cannot produce variation from them, and harmful genes will pass it on to their offspring.

If this gene is inherited in an autosomal recessive manner, its children may develop disease because they are mutant homozygotes. Therefore, inbreeding increases the risk of some autosomal recessive diseases.

Mao let the patriarch certainly don't know.

After hearing Xiao Chen's explanation, Mao asked the patriarch to say, ”Dr. Xiao, do you mean you can't get married within four generations?”

”Yes, you'd better not get married. I think you'd better marry the Miao people outside. The young women of the Miao people outside can marry in, and the young women here don't marry out, so it won't lead to close relatives, and harmful genes are easier to pass on to future generations. ”

Marry the women here?

Let the women outside marry in again?

Tribes and others never seem to think about it.

Now they still live a life of slash and burn cultivation and isolation from the world. If they marry like this, can't they maintain the traditional culture?

Mao asked the patriarch to frown.

”Dr. Xiao, is there any other way besides this?”

”No. Otherwise, there will be fewer and fewer people in your tribe, and those of your descendants will have more and more genetic diseases and more pain. It must be harder to suffer from pain. ”

Xiao Chen feels that the nine Li people can keep their traditions, such as good essence culture can be preserved, and they will not be abandoned.

Like the marriage of close relatives, it must not work in Xiao Chen's opinion.

In fact, this kind of situation also exists abroad. There are such tribes in the Amazon jungle. They live the same life as the Jiuli nationality, and finally disappear slowly, because there is no one.

No one, naturally there is no tribe.

”Dr. Xiao, what do they do?”

”According to their symptoms, I give them medicine to drink. Some can be cured, but others can't be cured.”

Xiao Chen knows that his medical skills are very good, even in the late stage of cancer. As long as he wants to treat them, he can be completely cured.

However, this requires mysterious medicine and needs to pay a price.

Strange diseases like these in front of us.

Many did not exist, but now they appear in the ordinary people of these tribes, which is caused by their close relatives' marriage.

Xiao Chen gave them prescriptions one by one and asked them to buy at the small town drugstore outside.

In the mountains, although many can be used as medicinal materials, decoct medicine soup and drink it.

However, in fact, we can't have all the herbs here. We still have to go to the drugstore outside to buy them.

Maybe it was because of what Xiao Chen said. Mao asked the patriarch to meditate and asked people to entertain Xiao Chen. When they went to a wooden house, Xiao Chen had seen master Miao.
