Zhao Mengqi's genetic hypothesis would probably have been ridiculed if he had said it elsewhere at another time.
At this time, everyone had witnessed the success of the blood transfusion method with their own eyes, so there was no doubt about Zhao Mengqi.
Following what Zhao Mengqi said, Dr. Chong also figured out some ideas.
"Because genes are paired, two equivalent genes may or may not be the same. Therefore, parents and children may have different blood types, and the probability is very high. There will also be differences between brothers and sisters. No wonder siblings have both Similar yet different..."
"As far as blood type is concerned, a person is of the heaven type, but in fact there are two combinations of "tiantian" and "celestial being". The same is true for the earth type. Suppose the father is of the heaven type and the mother is of the earth type, but they reproduce There are not only "Heaven" and "Earth" genes, but also "Human" genes. After recombination, all four blood types may actually appear! "
"Your Highness said that when different blood types are mixed together, each other's antibodies and antigens will fight, resulting in coagulation and precipitation. Only blood of the same type will get along more harmoniously, as it should be."
"Therefore, the method of combining blood in identifying relatives by shedding blood is actually not reliable! This...aren't it possible that many of the cases that were judged based on this method in the past were unjust, false, and wrongly decided!?"
"It's a pity that Song Tixing left a few years ago and was unable to listen to His Highness's wise words and correct the errors in "A Collection of Wrongs"..."
The Song Ti Xing mentioned by Imperial Physician Chong was Song Ci, who died four years ago while serving as the economic and strategic pacifier of Guangzhou. Although Song Ci also served as a military and political officer, he mostly held official positions in judicial, criminal and prison matters, and also had orders in this regard. This is a remarkable achievement, so most people are accustomed to respectfully calling him "Song Tixing", even in the epitaph.
Although his "Resolution of Wrongs" is limited by the times and has flaws and omissions in some places, its status in forensic medicine is unshakable, and it will be a must-read for forensic medicine even in later generations.
"It doesn't matter if there are some mistakes. Any progress is made through continuous trial and error and accumulation. It is the contributions of great ancestors one after another that allow us to stand higher and see further. At the same time, we ourselves must be brave enough to explore and innovate, and don’t be afraid of making mistakes, because even if we make mistakes, we can provide valuable experience for future generations!”
Zhao Mengqi felt that in this era, doctors should be the most receptive to scientific thinking. After all, exploring the true meaning of life is science, so he took the trouble to guide them.
"In a word, only through practice can we gain true knowledge. No matter how beautiful the idea is, if it cannot withstand the actual test, it is just a fantasy and has no meaning in the world."
These words made Dr. Chong think deeply and immediately kept them in mind.
Perhaps the atmosphere at this time was in place, which triggered everyone's thoughts about genes, and everyone wanted to get King Yan's opinions and suggestions, so Chongzhi, the nephew and apprentice of Imperial Physician Chong, stood up and saluted Zhao Mengqi.
"Your Highness, the student thinks that the principle of inheritance has actually been known to people for a long time. It is said that "dragons give birth to dragons, phoenixes give birth to phoenixes, and mice give birth to burrows in the ground." They also apply this principle to the cultivation of livestock and crops, but because they do not know the existence of genes, Therefore, it is less targeted, mostly relies on luck, and is less efficient, and it takes a long time to get results. "
Seeing that King Yan listened carefully and nodded slightly to encourage him to speak, Chongzhi put aside all his worries and spoke freely.
"The student is thinking that His Highness said that there is no difference between good and bad genes, but those that adapt to the environment are more likely to be retained. Therefore, the same species in different regions will have differences, and there is a saying that oranges grow in the north and south."
"And artificial selection is actually a kind of environment. Therefore, through purposeful screening, the genes that people need can be purified and then used to reproduce better offspring."
"For example, if you want natural-type blood, then only natural-type and natural-type blood can be paired and reproduced. Although natural-type blood also originally carries human genes, after several generations of targeted screening, the human genes will be Completely remove it, leaving only the natural genes, so that offspring with fixed traits can be bred in a planned way..."
Chongzhi talked for a long time and expressed his thoughts on species selection. Even though the idea was still very rough, Zhao Mengqi admired this idea very much.
"You are right, human intervention does affect
It has caused the evolution of many species. In nature, individuals who are stronger and more adaptable to the environment usually have higher priority in reproduction. Therefore, wild species often have stronger survival ability, but this is not the case in captivity. After one generation after another, Selection will generally lead to development in a direction that is more beneficial to people. "
"Of course, there are counter-interventions. Take the horse administration of the Song Dynasty as an example. Horses need to be good enough to become war horses. However, because of the needs of the battlefield, war horses are usually castrated, so only worse horses have the chance to breed. , this caused the quality of the entire group of horses to decline, and they had no choice but to lower the standards of war horses and cut off the best ones. From this vicious cycle, the war horses of the Song Dynasty became more and more unbearable."
As he said that, Zhao Mengqi expressed some emotion about the current Ma Zheng, and then continued to talk about the topic.
"Speaking of which, your idea is very valuable. It is very feasible to use purification to breed species! Of course, everything exists for a reason. When you completely remove different genes, it is possible for the species to be cultivated to have certain There are shortcomings in all aspects, but there are gains and losses, which are the principles of heaven and earth."
"In addition, the combination of different genes may also produce different effects. Therefore, species can also be improved through means such as hybridization, and methods such as purification and hybridization can be used organically, which may create a new world..."
Seeing that his idea had been affirmed and encouraged by King Yan, Chongzhi suddenly became very excited. As soon as his mind became hot, he said to Dr. Chong, "Uncle, my nephew no longer wants to study medicine. I want to study the reproduction of species!"
As if he was afraid of not getting approval, he immediately thought of an important reason as a bargaining chip, "If my nephew can really make a name for himself, then he can breed the best war horses for the Song Dynasty in the future!"
What the hell?
Why do you keep saying that you don’t want to study medicine?
Your boy is the most talented in studying medicine among the younger generation of the Chong family. I also want to train you to become the pillar of the Chong family for the next generation!
Imperial Physician Chong was a little dumbfounded, and he didn't know King Yan's intentions, so he didn't dare to object easily. He just looked at King Yan eagerly, his eyes full of pleading.
Are you looking at ***?
I didn't mean to kidnap your nephew.
Zhao Mengqi touched his nose unnaturally, "Ahem, Chongzhi, don't be too ambitious..."
Your Highness is indeed a kind person.
Dr. Chong's eyes were filled with gratitude.
Chongzhi's eyes darkened, as if he had ambitions that were hard to reach...
But Zhao Mengqi changed his words and said, "I support the direction you want to research, but if you achieve success, it will not only benefit the world, but also create a brand new knowledge."
"But I think you don't have to give up studying medicine. After all, knowledge always has something in common, and medical knowledge can also help your new research. You can study medicine and start new research at the same time without delay..."
"Well, I originally planned to reform Pingjiang Fuxue to include industry, agriculture, commerce, medicine and other knowledge, and simply add a biology department. If you are really interested in this, you can try to be the person in charge. If you really achieve results, then you can Grant you an official title!"
China has always had an official-centered mentality, so outstanding talents from past dynasties have entered the officialdom and never looked back.
If you want to introduce talents to new disciplines, luring them with official positions and titles should be the most effective and direct way.
"In addition, I think it is still difficult to start with horses from the beginning. The breeding cycle is too long and it is still a single litter, which is not good for initial research. I suggest that you choose a species with a short breeding cycle and a large number of offspring, such as pigs. ,mouse……"
Imperial Physician Chong was so sad that he wanted to cry when he saw King Yan talking.
Doesn't this still lead people astray?
What to do with the next generation of the Chong family?
It seems that the only option is to have one's son brought to his side and trained as early as possible.
After talking for a quarter of an hour, Chongzhi memorized more than ten pages, as if he had found a treasure.
After talking so much again, Zhao Mengqi felt his mouth dry, so he picked up the teacup and brought it to his mouth.
At this time, Zhao Fei, who had transformed from a clever kid into a curious baby, came over with a pair of big eyes blinking.
"Fourth brother, the hybrid you are talking about is not the kind of horse and donkey, right? This mule has the advantages of both a horse and a donkey. It seems that hybridization can indeed improve species. Is that person..."
"puff……"
A mouthful of tea squirted all over Zhao Fei's head and face.
"Stop it! This is not fun to talk about or think about!"
I'm a good boy!
This girl has all kinds of weird things in her little head, and she actually has such a bold idea, ***...
Zhao Mengqi trembled, shook his head, and quickly shook off the discordant picture.
Zhao Fei didn't bother to wipe her face and let the tea flow from her forehead to the bridge of her nose, and then drip from the tip of her slightly upturned nose. She looked aggrieved and confused, "Why!?"
"This is a taboo of human ethics and must not be touched. Besides, it is actually a relatively rare example that horses and donkeys can produce cross-species offspring. Most cross-species crosses will not produce offspring, especially between animals. , and the vast majority of mules have no reproductive capacity and cannot continue to reproduce the population. Strictly speaking, they are not an independent species."
"Why!?" Zhao Fei still turned on the curious baby mode.
"Well...this involves reproductive isolation, and this is also the biggest feature that distinguishes different species...."
Zhao Hui's big eyes blinked, "Why is there reproductive isolation?"
Is this girl the reincarnation of a hundred thousand people?
"Well, I guess, there was only one kind of simplest creature in the world at first. But because of the variability of genes, different descendants gradually emerged. Some of them could adapt to the environment and survived. Over a long period of time, Continue to evolve... There are different environments and different opportunities in this world. In short, it is natural selection and survival of the fittest."
Zhao Mengqi had no choice but to talk nonsense about Tianyan theory.
"When they evolved into different species, their genetic differences became increasingly larger and more complex, so they could not be matched together, so there was reproductive isolation... Horses and donkeys should have evolved from the same species, and have many traits with each other. They are very similar. The genetic differences may be relatively small, so they can barely match, but there are still differences after all, so the mule cannot carry out meiosis with such forcibly matched genes..."
Zhao Hui actually seemed to understand and murmured, "So that's it. Are all living things from the same origin? Natural selection, survival of the fittest? It seems very interesting."
Then she clapped her hands together, and her eyes burst out with blazing fire, "Fourth brother, I have decided, I will study this theory of heavenly evolution from now on!"
Walter?
You want to be a female version of Darwin! ?
I wonder if Lao Zhao will beat me to death when he sees the strange changes in his baby daughter?
Forget it, it's better than touching the taboo, just let her go...
Zhao Mengqi held his forehead, feeling that he had released something great.
At this time, a voice came from a person, "Yi has Tai Chi, which gives rise to two rites, two rites give rise to four images, four signs give rise to Bagua, and then there are all things. What Your Highness said is that all living things have the same origin. It seems to make sense..."
