Chapter 400: Clarifying Blood Relationship (Please vote and subscribe)
Two versions of nursery rhymes and a kinship genealogy were posted on three wooden boards, but the clan leaders could not understand them. Most of them had just joined the Han tribe for a few months, and the only few words they knew were those that Luo Chong had passed on through commodities.
Seeing their eyes wide open, Luo Chong had to read them in person, and then explained the blood relationship one by one to the drawing beside them, from ancestors, parents, peers, to children and grandchildren.
He then solemnly warned them that aunts and cousins were not allowed to marry within three generations, and aunts and cousins were required to marry more than five generations, otherwise there was a high probability of infertility, or congenital mental retardation, physical disability, malignant genetic diseases and other adverse consequences, which surprised everyone.
"Chief, I understand not being able to have children, and I also understand physical disability, but what are congenital mental retardation and genetic diseases?" The clan leader of the Zong clan asked first, and the other clan leaders nodded one after another, indicating that this was also the question they wanted to know.
"It's easy to understand what it means to be born mentally retarded. It means that you are born a fool and can't learn anything, even talking and walking. Or you are born young and your IQ remains at the level of a child. You will never learn adult things. This is also considered a disability. A mentally retarded child can only waste food when born, and will also be a burden for adults to take care of. So we should try to avoid such things from happening. Otherwise, it will be a burden for any family to have such a child." Luo Chong explained to them.
However, the clan leaders below didn't agree. They didn't know whether Luo Chong's suggestion of avoiding the probability of mentally retarded children being born through blood ties would work, but they had seen such children born with disabilities and even "dealt with" them personally.
Waste food? Burden adults? This is impossible. They will not raise such disabled people to add burden to the tribe. In the past, in their own tribe, when such a situation occurred, they would either kill the baby for sacrifice and pray for the gods' forgiveness, or simply abandon it in the wilderness and let it fend for itself.
The leader actually wanted to keep them alive. However
, the Han tribe was not short of food for one or two people, so they did not refute, but asked another question.
"Leader, what is the last genetic disease?"
"Haha, when it comes to genetics, this is the most amazing." Luo Chong pointed to the relationship on the map and continued to explain to them.
"Well... Take the patriarch of the Zong clan for example. There is a wrinkle on your eyelids that looks like double eyelids. Then the child born to you by your woman is very likely to also have double eyelids. This is called inheritance, and it is also a symbol of blood continuation. It is also the reason why I let all the clan members separate according to family, because it is easier to distinguish blood relationships.
In addition, if the mother of the child also has double eyelids, then the probability of the child having double eyelids will be greater. Of course, this is not absolute, but it is just a little more likely.
There is also a situation where the child does not look like the parents, but looks like the grandparents, or the child does not look like the parents, but the grandchildren look like you. This situation is called intergenerational inheritance.
And this intergenerational inheritance sometimes skips several generations, which is uncontrollable, but more or less some of the characteristics of the parents will be inherited, sometimes it is appearance, sometimes it is body shape, and even if you have a mole on your body, the child may grow a mole in the same position.
However, although this kind of inheritance is a symbol of the continuation of blood, it can sometimes bring trouble. For example, if the parents have some disabilities, such as being born deaf, that is, the ears cannot hear sounds, or the mouth cannot speak, then the child may also inherit this disability, or even not only the disability, but also the serious illness. You know, serious illnesses are some diseases that are difficult to cure.
In this case, sometimes the first generation may not be able to see anything, and it becomes inherited from the previous generation, or it will be hidden forever, and there will be no disease in the next many generations. However, if
it is inbreeding, this kind of elder's serious illness is likely to appear in the next generation. In general, inbreeding will turn recessive genes, uh, recessive inheritance into dominant inheritance, which means that it can be seen by people. "Luo Chong wanted to say genes, but when he remembered that they didn't understand, he had to change the word.
Of course, although they don't understand now, the next generation may not understand. Luo Chong has planned to compile the genetic inheritance in the biology of junior high school in the previous life into the textbooks, which is also to popularize science to all the tribesmen and let them know the harm of inbreeding.
"You can understand what I said, right? "Luo Chong looked at the crowd, some of whom suddenly realized, some were puzzled, and some had an expression of admiration. He wondered how much they could understand about such hard-core genetics.
"Well, I understand. The chief is right. My children look very much like me. Some look like their mothers. There are also what the chief just said about intergenerational inheritance. They look very much like my dead father. This should be what the chief said about blood inheritance." The patriarch of the Hu clan said first.
"Well, after listening to what Chief Hu said, I understand. I have a black spot on my arm, which is the mole the chief said. My child also has one on the same position on his arm. This inheritance is really weird." Chief Ao also said.
"Yes, this is heredity, but heredity will not choose good or bad for you. It only inherits advantages and not disadvantages. If parents or elders have diseases, they will also be inherited. Moreover, this situation occurs most frequently during inbreeding, so you all understand what I mean. "Luo Chong nodded and said to them.
With these people's personal experience, I believe they can quickly figure out the relationship.
"Well, we all understand the relationship the leader said, but what should the tribe members who have just reached adulthood do when they find a spouse in the future to know whether they are blood relatives, and now there are so many people in our Han tribe, and it is not easy to distinguish blood relations." The patriarch of the Chai clan concluded.
"Yes, it is indeed difficult to distinguish, so I asked you to come here for this matter.
I plan to let all the tribe members learn to recognize their relatives by rank before this winter, so that they can sort out their blood relations by themselves, because their parents and children are not clearer than themselves, and then after all the tribe members have learned to rank their generations, when there is nothing to do in winter, I will organize a census of the whole tribe, register everyone's identity, and determine their blood relations." Luo Chong stated the ultimate goal of this time.
"This, all learn these Chinese characters, isn't it too difficult? It is unlikely to let all the tribe members learn before winter? ! "The tribe leaders showed surprised expressions.
