Origin

Dean Wang's voice was full of shock, Wu Zhongyuan couldn't hear what was said on the other end of the phone, but Dean Wang said again, "One more pair or one? Which two? Don't say it, you Immediately fax the inspection report to me, and by the way, the samples sent for inspection will also be brought back."

After saying this, Dean Wang hung up the phone.

Seeing Wu Zhongyuan's puzzled face, Dean Wang didn't hide it, "Your blood test results are out."

"How is it?" Wu Zhongyuan asked nervously. President Wang is over 60 this year, and the test results that shocked him are definitely not good results.

Dean Wang picked up his mobile phone and took a picture of the tattoo on Wu Zhongyuan's chest. He turned around and walked out, "I'll go get the inspection report right away. You sit down for a while, and I'll be back soon."

After Dean Wang left, Wu Zhongyuan looked at Dean Li and Head Nurse Zhang. Although the two tried to stay calm, they could still see that they were nervous.

"Director Li." Wu Zhongyuan looked at Director Li.

Hearing Wu Zhongyuan calling her, Director Li had panic in his eyes.

"The 24 pairs that President Wang said are chromosomes?" Wu Zhongyuan asked again.

Director Li did not answer, but she did, because her surprised expression showed that Wu Zhongyuan guessed right.

After confirming that he guessed correctly, Wu Zhongyuan calmed down, "It's not hard to guess, except for chromosomes, other inspection items don't seem to be described as 'right'. Besides, you are a county hospital, except for DNA, everything else should be I can check."

After Wu Zhongyuan finished speaking, Director Li said unnaturally, "Chromosomes and DNA are not the same concept, but don't worry, cases of chromosomal abnormalities are not uncommon."

"You seem to be more nervous than me," Wu Zhongyuan forced himself to smile, "If it's a common abnormality, President Wang won't be so surprised."

Director Li did not answer.

"I'm not a child anymore." Wu Zhongyuan added another sentence, this sentence is a pun, the implication is that you don't try to fool me.

Dean Wang left for longer than Wu Zhongyuan expected. After waiting for more than 20 minutes, Dean Wang returned with a few pages of fax paper in his hand.

As soon as Dean Wang entered the door, the three of them looked at him nervously, to be precise, the inspection report in his hand.

President Wang did not show the inspection report to Director Li and Head Nurse Zhang, but said to them, "You guys stay away, I want to talk to him alone."

Director Wang's words were very straightforward. Director Li and Nurse Zhang had to leave. In fact, they didn't want to leave, at least not until they saw the inspection report.

When they left, Dean Wang walked to the door and was about to close the door. After thinking about it, he turned around and said to Wu Zhongyuan, "It's cool outside, let's go out for a walk."

"Okay." Wu Zhongyuan nodded in agreement, the environment in the ward made him feel very depressed.

Dean Wang took off his white coat and went downstairs with Wu Zhongyuan. The driver was still waiting downstairs. Dean Wang waved and let him go.

It was not dark at this time, but the peak time for get off work had passed, and there were not many people on the street. There were a few hawkers selling cold drinks and fruits in front of the hospital that had not closed their stalls. When they saw President Wang, they all stood up to greet him.

Dean Wang politely nodded at them, "Zhongyuan, you have to be a little mentally prepared."

"Are you going to lock me up?" Wu Zhongyuan was half-joking in order to ease the tension in his heart.

"It won't,

"President Wang shook his head," but the test result of your blood sample is very strange, I have never seen a similar situation. "

"My chromosome is abnormal?" Wu Zhongyuan asked. He is only a senior in high school. He knows about chromosomes, but he only knows about it.

"Yes," Dean Wang nodded. There was a library next to the hospital. The library was closed. Dean Wang walked up the steps and sat down from the upper steps. When Wu Zhongyuan sat down, he put the The inspection report was handed to him.

Wu Zhongyuan took over the inspection report. Since it was a faxed document, several reports were linked together, and the numbers and words on it were not particularly clear.

Wu Zhongyuan didn't read it in detail, and after a few glances, he returned the inspection report to President Wang, "Tell me about it."

Seeing Wu Zhongyuan trusting him so much, Dean Wang was very pleased, and his sincerity earned Wu Zhongyuan's trust.

"This sounds complicated, I'll try to keep it simple," Dean Wang coughed dryly and cleared his throat, "Chromosome is a substance in the nucleus, its main function is to carry genetic information, through the detection of a person's chromosomes, You can make a relatively accurate judgment on the person's race, blood type, blood relationship and other information, normal chromosomes exist in pairs, ordinary people have 23 pairs of chromosomes, 22 pairs are shared by males and females, and the remaining pair determines gender."

Wu Zhongyuan did not interrupt.

Dean Wang also said, "The common chromosomal abnormality is usually one more than 23 pairs, that is, 47, and there are many reasons for it. Parents have diseases, drug abuse, and older childbirth may lead to chromosomes. Abnormal, chromosomal abnormalities often accompany intellectual and developmental disabilities…”

When President Wang said this, he stopped talking. Someone came up from the sidewalk below. It was a hawker selling cold drinks. He graciously brought two bottles of mineral water. "President Wang, drink some water."

Dean Wang got up and refused, and the hawker put down the mineral water and ran away in a hurry.

After the hawker left, Dean Wang continued, "I just said that 47 chromosomes are the most common chromosomal abnormality. There are also 48 chromosomes, but they are no longer in pairs. The biggest difference between your situation and previous cases is not that much. two chromosomes, but the two chromosomes out of the 23 pairs are paired."

"Why do they appear in pairs?" Wu Zhongyuan asked eagerly.

"I don't know, there is no similar case for your case to refer to." Dean Wang slowly shook his head.

"You just said that by testing chromosomes, you can determine what nationality a person is." Wu Zhongyuan said.

"Race and ethnicity are not the same concept," President Wang corrected himself. "Through the test of your normal 23 pairs of chromosomes, it has been determined that you are a Han nationality in the narrow sense."

"What is the narrow sense of Han people?" Wu Zhongyuan didn't quite understand.

"It's the part of Han people whose ancestors have never intermarried with ethnic minorities. The number of these people is not many, but it's not too small." Dean Wang explained patiently.

After listening to Dean Wang's explanation, Wu Zhongyuan felt a little light, "Then what happened to my extra pair of chromosomes?"

President Wang unscrewed a bottle of mineral water and handed it to Wu Zhongyuan, "You have lost too much blood, we thought about transfusion for you at first, the blood transfusion procedures in regular hospitals are very strict, and detailed blood tests are required before blood transfusion. The blood samples tested are collected from your wound. The test indicators are very different from the normal indicators. Due to the limitation of the testing equipment, we cannot conduct further analysis. We can only send people to the provincial capital for testing, in order to find out. The exact cause of your abnormal blood."

Seeing that Wu Zhongyuan wanted to interrupt, President Wang raised his hand, "Our hospital's testing equipment is not top-notch, and it is impossible to distinguish whether the abnormal components in your blood are inherent or mixed with trauma. Let me give an example of being bitten by a mad dog. The blood flowing out of the wound may be mixed with the genetic components of the dog, and at this time, the intervention of more sophisticated testing equipment is required to distinguish."

"My head was injured by an iron pipe," Wu Zhongyuan said.

Dean Wang nodded, "These are no longer important. Now the test results have come out. Your chromosomal abnormality is from congenital inheritance, and it is not a disease."

"What do you mean?" Wu Zhongyuan wondered.

"You are healthy and normal, but this kind of health and normality are only relative." Dean Wang said.

"What is relative?" Wu Zhongyuan was at a loss.

Dean Wang did not answer immediately.

Wu Zhongyuan stared at President Wang, waiting for him to answer.

After hesitating for a long time, Dean Wang finally said, "The so-called relative means that although you are developing normally, due to the particularity of your genes, if the XY chromosomes in your body are combined with the female's XX chromosomes, the offspring may produce unpredictable mutations. ."

Wu Zhongyuan was stunned, "You mean if I get married, the children born will be monsters?"

"No, no," Dean Wang waved his hands again and again, "Mutation is not necessarily bad, it may also be a good development. We must know that we humans have also undergone many mutations in the long evolutionary process."

Accepting so many unacceptable things all at once, Wu Zhongyuan was a little stunned, and he didn't know what to say for a while.

Dean Wang patted his shoulder again, "Be strong."

Wu Zhongyuan nodded and took a sip.

"We have also tested the extra pair of chromosomes you have." Dean Wang said proactively.

"What's the result?" Wu Zhongyuan asked.

"The two extra chromosomes you have inherited are inherited from your father and mother respectively. These two chromosomes belong to two different unknown organisms, and they do not completely match the gene maps of known species recorded in the province. In addition, cross-species Genetic breeding is also inexplicable in terms of genetics." Dean Wang's face was also full of doubts.

Wu Zhongyuan nodded blankly, after tossing for a day, he was already exhausted, "President Wang, can you put it simply, I'm a little confused."

"I also want to answer your question, but I can't figure it out myself. That's it for today, I'll ask the driver to take you back." Dean Wang took out his mobile phone and called the driver.

"President Wang, I still have a question." Wu Zhongyuan said.

Dean Wang tilted his head to look at him.

"Why are you being so kind to me? You can absolutely not tell me about these things." Wu Zhongyuan said.

"I really don't need to tell you, but I hope to gain your trust and cooperation," Dean Wang said frankly. "Your condition is extremely rare, and it has extremely high research value for both medicine and genetics."

Although Dean Wang was sincere, Wu Zhongyuan still felt a little prickly in his heart. After all, being studied by others is not always a pleasant thing.

Soon, the driver drove over, and Dean Wang stood up and walked down the steps with Wu Zhongyuan, "How is your academic performance? The college entrance examination is coming soon, are you sure?"

"It's okay." Wu Zhongyuan replied casually.

"Have you thought about the major you want to apply for?" Dean Wang asked again.

Wu Zhongyuan shook his head. He wanted to apply for the military academy and the police academy most, without paying tuition fees. After graduation, he would be an officer and a police officer. Unfortunately, he could only think about it, because neither type of school would admit candidates with tattoos.

"Go back and pay attention to rest and study with peace of mind. If there is any new progress in the genetic map comparison, I will try to notify you." Dean Wang said.

Wu Zhongyuan nodded. After nodding, he suddenly remembered something, "You just said that the two extra chromosomes I created don't completely match the known species?"

"Yes." Dean Wang said.

"Are there any similarities?" Wu Zhongyuan asked.

"You lack understanding of genes," Dean Wang said, shaking his head, "The genes of many species are very similar, and our genes are very similar to those of gorillas. Sometimes just a little genetic difference may lead to individual and morphological differences. A huge difference."

"Oh." Wu Zhongyuan nodded blankly.

Seeing Wu Zhongyuan's frustration, Dean Wang added, "There is indeed no specific result of the comparison. Now it is difficult to determine the exact source of these two chromosomes, only the species they belong to."

"What kind?" Wu Zhongyuan asked.

"The two extra chromosomes you have come from mammals and birds are..."
