Xianyu Infrastructure, I have a lot of troops in my hands

"But there is still a saying that cousins ​​should be married to each other. So I have a question: can cousin marriage prevent genetic diseases in offspring?"

Xie Xian lowered her eyes, still unable to overcome the hurdle in her heart, and finally asked.

The students sitting below were whispering, and someone raised his hand, "Madam Xian, what is a genetic disease?"

Xie Xian was afraid that they didn't take it seriously enough, so she patiently replied, "White ghost disease, heart disease, short life span, children born with congenital deformities, intellectual disabilities, and even worse, they can't give birth to healthy offspring."

Every time she spoke, the faces of the people below became more serious. In ancient times, population was always a national issue, and matters affecting population had to be taken seriously no matter how small.

Some of the girls have begun to stagger, as if they were remembering something bad.

Xie Yao asked: "Will it be like this as long as they are close relatives?" Her voice trembled a little. Regardless of whether what Xie Xian said was true or false, as long as there was even the slightest possibility, it would definitely shock everyone.

Xie Xian was still as casual as ever. In her opinion, it was nothing for everyone to discuss such common sense issues.

"This is a question of probability. All we can say is that the closer the blood relationship, the higher the chance of the offspring getting the disease." As for whether they believe it or not, it's none of her business.

"Oh my god, no wonder..." Who among the noble families doesn't have a few cousins ​​through marriage? If you think about it carefully, it's just as Xie Xian said.

"But we can't generalize this! I've seen several couples who are not related by blood and their children have difficulty surviving. How do you explain this?" Naturally, there were those who disagreed.

Xie Xian nodded. It was normal to have objections to the questions raised. She began to praise.

"This student is good at thinking, which is good. Then let's do a population survey!" she suggested.

"The diseases I mentioned are also common among ordinary people, and the offspring of close relatives have a higher chance of getting the disease than ordinary people."

"Then today's homework is to calculate this probability. Each of you should go back and investigate one or two close relatives. Please be careful not to tell us our guess when you are doing your work. We are just speculating now, and all the results will be announced next time."

Xie Xian calmly assigned the assignment, "On the impact of marriage between direct and collateral relatives within three generations on future generations." The topic was thus established.

The Xie family has been deeply rooted in Que County for many years and has a wide network of contacts. Every family has a few cousins. In Xie Xian's words, the samples collected should be as free of duplication as possible.

Xie Yao even suggested asking Mrs. Lu for help, as matchmakers, midwives, or female doctors must have many sources of information.

This proposal greatly boosted the spirits of the female students. They had a natural advantage in dealing with family matters and household affairs, and naturally did not want to be dominated by the men.

Everyone is eager to give a good performance.

At this moment, no one mentioned the matter of removing the bead curtain.

Xie Wenfeng gritted his teeth secretly. Would he be ostracized by everyone just because he said something he disagreed with?

The second wife's daughter was so angry that, in order to prove that what she said was wrong, she even made up a story that third cousins ​​could not marry each other to fool everyone.

Naturally, she didn't believe it. Unexpectedly, the men actually listened to her. To her, it was simply ridiculous. The purpose of cousin marriage was to strengthen the relationship between the families. Even if it was detrimental to future generations, the only things sacrificed were the children.

Her mother once said that women like us are like dodder flowers. We rely on our fathers and brothers at home and on our husbands when we go out. If we try to be strong on our own, we will end up with nothing.

Her purpose of coming to Shuziting was to find a good husband. Xie Xian's proposal would ruin her good fortune.

For the first time, all the students of Shuzitong received a social practice class, and this assignment was closely related to themselves.

After Xie Xian assigned the homework, she forgot about it. She was just giving it a start. If someone was attentive, they would naturally discover the tragic truth behind the data comparison.

As for those who don't believe, it's not her turn to worry about it, but she is unintentional and has achieved great success.

In less than two days, the news spread like a plague. Even the homework that Xie Xian assigned to the students, "The impact of marriages between direct and collateral relatives within three generations on future generations," was simply referred to as "the theory of blood relationship," and became the most popular topic in Que County.

The theory of blood relationship is closely related to people's lives. Some cousins ​​who have been engaged for many years, and some who are preparing for a wedding, put down what they were doing and waited for a result when they heard this.

Some people sneer at it, while others are good at seeking evidence.

"Wow, so the root is here." A woman burst into tears upon hearing this.

"Isn't that from the Su family? Oh, she and her family are cousins. I heard that they have been married for seven or eight years, but they keep losing their children every time they get pregnant. Wow." Some people were secretly amazed. Most people in the city knew this woman from the Su family, but she couldn't hold her head up in front of her husband's family because of her child.

But every time she went to see the doctor, the doctor said that although she was in good health, the fetus in her belly would miscarry within two months. Everyone could not find the cause and finally concluded that it was a woman's destiny to have no children.

"Well, just treat it as a joke, how can you take it seriously?" The man who spoke very loudly just now suddenly felt guilty. This news was only a rumor, and the final outcome of Xie Jiashu Zitang had not yet come out.

But seeing the appearance of the Su family girl, everyone believed it. Some women who were interested in doing good gathered together and searched all the families in the village where their cousins ​​were getting married.

It’s true that nearly half of the people’s children have some problems, of course there are also normal ones. “According to this, almost half of the children have problems. It’s really scary.”

An old woman patted her chest. She had worked as a matchmaker in her early years, but fortunately she could make ends meet and stopped doing it. "It's a good thing, old man, I don't have to do the matchmaker job anymore. If it were so, I don't know how many bad relationships I would have had!"

The people around also sighed when they heard this. Usually, when they encountered difficulties in having children at home, they never thought about this aspect. But when it was suddenly mentioned to them, they discovered that the truth was often even more cruel.

In the government office of Que County.

"Have the statistical results of this matter come out?" Bai Lingjun was pacing anxiously in the lobby at this moment.

Xie Ze had two deep dark circles under his eyes on his round, fair face. He took a sip of strong tea and glanced at the tea leaves in it with some disgust.

"Household Registration Department, we have been working overtime since last night," at least let people have a break!

"Quickly make some strong tea and send it over!"

Xie Ze was choked and said unhappily, "The result from Xie Jiashu Zitang's case hasn't come out yet. Why is the county magistrate so anxious?" Why are you so panicked?

"Hey, your Xie family only counts the Xie clan members, so how can you accurately count the entire county's population?"

Xie Ze, yes, yes, yes.
