there are wolves

Chapter 10:

"The next one, let's look at the big topic"

"Hmm...big question, then I read it"

"Um"

“果蝇红眼对白眼为显性，控制这对性状的基因位于X染色体上。果蝇缺失1条Ⅳ号染色体仍能正常生存和繁殖，缺失2条则致死。一对都缺失1条Ⅳ号染色体的红眼果蝇杂交，图片F1中，A的白眼雄果蝇占1/4。B的红眼雌果蝇占1/4C．染色体数正常的红眼...”

Yu Wangran knocked on the table: "Stop, don't read the questions, read the questions"

Lin Shu'er held her chin and said drowsily: "After reading, let me find something to do, what should I do if I fall asleep later?"

Yu Wangran: "Quickly read, you read the questions for two self-study classes and did one class."

Lin Shuer opened her eyes vigorously, pulled herself together and continued to read the questions.

The self-study class in the afternoon was not usually supervised by a teacher. As the monitor, Yu Wangran and the study committee member Xue Mingyao organized the self-study class discipline a little bit. Everyone formed their own study groups, put the desks together and went to study separately. , This learning method is Xiangyang's first initiative. It gives students a certain amount of freedom and space to study independently, and it also helps them to be freed from the high-intensity progress of nine large classes a day. To a certain extent, it is beneficial for them to relax, but the effect Get twice the result with half the effort.

At first, when Xiang Yang was conducting experiments in his own class, the school leaders did not support them, and insisted on filling up the timetable, teachers of each subject taking turns to maintain a high-intensity pattern, saying that letting students go will only make them lazy and slack.

Xiang Yang disagreed with this traditional education model 120 times, and broke up after a few words with the teaching director. Although he didn't get support, he didn't give up. He called his confidant assistant Yu Wangran and study committee member Xue Mingyao, The three of them held a meeting all afternoon during a physical education class and came to a conclusion.

"The superiors won't let us do it, let's do it ourselves, and when we make a name for ourselves, they won't object to us doing it."

Yu Wangran listened to him 'playing around' and was given a headache by him, so he interrupted him impatiently, and summed it up brilliantly: "Seize power by armed forces, encircle the cities from the countryside?"

Xiang Yang snapped his fingers: "Yes! That's what it means, classmate Yu Wangran can change his name to Mr. Wolong."

So their experimental Class [-] became the base of a small revolutionary group dominated by Xiangyang, and quietly supported this new model. At first, the students were really loose. With strict management and Yu Wangran's assistance, discipline was gradually established, and this "freedom model" gradually matured. After more than a month, the students all accepted and obeyed Teacher Xiang's "freedom school" The rules and the atmosphere are getting better and better. It has developed to the present, and it is basically not used for the management of Wang Ran and other class cadres.

As soon as the experiment in the second experimental class was successful, it quickly passed the review and approval of the superiors. The school leaders began to implement this new form of education in the whole school. It is strange that the humanized education model is not popular. Students are very accepting and willing to cooperate. This system has been used until now.

Xue Mingyao and a female student with a middle grade in the class temporarily set up a group, and sat next to Yu Wangran and Lin Shuer. The female student admired Xue Mingyao's proficient math ability, and while listening to his lectures, she used The eyes of worshiping the god secretly looked up at him.

Lin Shuer was still earnestly reading the questions, and Yu Wangran went to sweep the math papers spread out on Xue Mingyao's desk in a leisurely manner, and found that the question he was teaching the girl was exactly what he had done the day before. The problem he encountered at night, at that time, he had to think hard for a long time before he found a breakthrough in the conclusion of the problem. At this time, listening to him explain his thinking was much simpler and easier to understand than what he found. Sighing in my heart, Xue Mingyao's title of mathematical genius is really not just made up blindly, he is a genius in mathematics.

"What is the probability of death of white-eyed Drosophila in the absence of one chromosome IV?"

Lin Shuer let out a sigh of relief: "After reading, my answer is [-]/[-], right?"

Yu Wangran didn't directly tell her if it was right or not, but drew a sketch of the genetic ratio on the draft paper, and took a pen to tick it off: "Look, first of all, there is no interaction between chromosome IV and chromosome X, So the shape of eye color and the inheritance of chromosome IV are independent of each other..."

Yu Wangran spoke very carefully, and Lin Shuer listened very carefully. It took more than half an hour to solve a problem about the theory of genetic inheritance.

Lin Shuer bit her pen and looked at the genetic ratio diagram drawn by Yu Wangran on the draft paper, and said with a click: "It's not so absolute, if it is judged according to the dominant genetic inheritance, mental illness is a dominant inheritance ? Or recessive inheritance?"

Yu Wangran put the question book together, and said indifferently: "Your problem is a problem. Does mental illness have to be hereditary? This issue has been debated until now, so don't define it."

It is rare to come across a topic of interest to me, Lin Shuer is very interested in discussing it with him at this time, and said: "I think it is genetic inheritance, um... such as mental illness, although many people are induced psychosis , but if there is no gene to carry, how can it be induced?"

Yu Wangran heard that what she said made some sense, so he closed the book, thought about her words, and said seriously: "I disagree, according to what you said, the induction must be a recessive gene, if the recessive gene is The source of the predisposing body, isn’t it true that we are all carriers of psychopathy predisposing bodies?”

What he said was too esoteric, Lin Shuer took a lot of effort to understand his logic, and felt that she was about to be speechless, so she slapped the table and said, "How can there be an egg without a chicken?"

"If a chicken lays an egg, will the chicken that lays the egg be able to give birth to another chicken? As the saying goes, the skirt, hairpin, widow, and widow have no ancestry, and the genes are also interruptible. How do you know that your genes are in the same line? , or has it gone through many twists and turns, and has a long history? Using genetic inheritance to define a carrier of mental illness is narrow”

Of course, Lin Shuer couldn't compete with him in terms of eloquence, but she was not easily persuaded by him. She shrugged and said, "Maybe, but I think this disease must have a protozoa, which is inseparable from genes."

Yu Wangran took out his mobile phone and put it under the table to fiddle with, buried his head and said: "What you said is also reasonable, and this situation cannot be ruled out." Then he raised his head and smiled: "What's wrong with mental illness, manic depression is so talented"

Lin Shu'er glared at him: "Fuck you, fuck me!"

Yu Wangran smiled: "I also think this sentence is basically nonsense."

Even if such patients with mental illness achieve something, their psychological state can never bear the praise and slander given to them by the society, and they cannot feel the meaning of their own existence and the meaning they bring to the society. Most of them are abnormally empty and fragile , because the survivors who carry the disease body are the patients themselves.

After the first self-study class was over, some people in the classroom got up and moved around in twos and threes. Yu Wangran took advantage of the crowd, turned his back to the classroom door, and quietly fiddled with his phone.

Lin Shu'er bit the pen cap and looked at him: "You didn't play with your mobile phone very much before, what's the matter recently? When you have free time, you hold your mobile phone and don't let it go. Who are you hooking up with?"

Yu Wangran ignored her, and logged into all his social accounts, intending to find clues about Luo Xunyi, because this person is really a bit mysterious, with unknown origins and solitary behavior, except for the dark-skinned high school senior. Boys bumped into him occasionally, hardly ever saw him with anyone else, only the 'bureaucratic boy' was famous, everyone else knew nothing about it.

But he is very famous, when asked about Luo Xunyi, few people said 'Who?I haven't heard of it', and asked a deeper level, and everyone said "I don't know about this".

Yu Wangran still didn't find anything, put away the phone and rolled his eyes in his heart, thinking that I'm just being idle.

Lin Shuer asked him what happened?Why did you droop your face all of a sudden?

Yu Wangran said: "It's nothing, it might be hated by one person"

"Who? Liu Xueying?"

"...what does it matter to her?"

Comrade Chao Chao, the sports committee member who was watching the wind at the door, suddenly jumped in with one leg on his feet: "Squad leader, someone is looking for you!"

Yu Wangran turned his head and looked over, just in time to see Liu Xueying appearing at the door, so he got up and walked over.

"You guys talk, I'll watch out for you"

Wang Chao leaned on the wall and jumped out again, with enthusiasm that made people want to kick his lame leg very much.

Yu Wangran rolled his eyes at him, and asked Liu Xueying, "What's the matter, is there something wrong?"

Liu Xueying stood by the wall with a few female companions, and said with a smile: "Well, my friend organized an event this weekend, and I would like to ask if you are interested in participating."

"what activity"

"Lake Cycling"

It's just...boring enough.

Yu Wangran thought so in his heart, but he didn't say it: "I may...don't have time"

The smile on Liu Xueying's face obviously dimmed a bit, she lowered her head and hugged her arms for a moment, then raised her smiling face and said, "Let's go together, we may go to the suburbs again, I've already rented a car for you."

A few female companions also helped Liu Xueying persuade him, you and I were messed up.

Just when Yu Wangran didn't know how to fight back, he saw Lin Shuer jumping over, smiling heartlessly: "Swimming in the lake? I'm going too, add me."

Liu Xueying glanced sideways at her, and said in a calm tone, "Yes, welcome."

Lin Shuer yelled to Xue Mingyao, who was buried in the papers in the classroom, "Xiaoyao, how about going to the lake by bicycle on weekends?"

Xue Mingyao raised his head from the book, adjusted his glasses and thought for a while, before making an "OK" gesture.

Lin Shuer clenched her fist: "YES!" Then she said to Liu Xueying: "Don't worry, we will all go"
