Counting the royal family in the Tang Dynasty, there are those who rob their father's women, those who accept their younger brothers' women, and those who sleep with their sons, which are very common.

In such a comparison, it is not so unusual for a niece to marry a cousin.

It's just that since the Li family is the maiden family of Zhao Zhen's biological mother, it means that Princess Fukang and her cousin of the Li family are also related, which is different from his cousin's cousin and cousin, and it is almost a collateral blood relative within three generations.

According to the concept of modern medicine, the marriage between direct blood relatives and collateral blood relatives can easily lead to genetic defects.

For example, if a genetic disease is recessive, and if A and a are used to indicate the dominant recessiveness, AA and Aa will both manifest as normal people, and aa will manifest as disease.

Suppose two Aa blood relatives get married, it is easy to have children!

Therefore, not only do you pay attention to hybridization in planting, but also pay attention to hybridization when you get married, and you can choose an excellent partner to be healthier and better when you are hybridized.

It's easy for close relatives to get married.

Su Lu took this to heart. After he honestly finished a day's class, he asked Zhao Zhongyun: "Is there a warm house in the palace?" It's the kind where you can grow vegetables all year round and control the temperature. ”

Zhao Zhongjun said honestly: "Yes, I also ate fresh vegetables given by the official family in winter. ”

Su Lu nodded.

Zhao Zhongjun said: "What's the matter? ”

Su Lu said: "I think of something, go back and sort out my thoughts before I tell you." ”

Zhao Zhongjun let out an "oh" and didn't ask any more obediently.

Su Lu returned home, took out his very useful golden finger and searched for it, and began to wave the book. He first expounded the hypothesis deduction method, and then began to copy the basic experiments of high school biology books, deducing and expounding the most basic principles of genetics.

This doctrine is destined to subvert many people's three views, after all, in this era, "aunt" is used to refer to parents-in-law, which shows that the combination of cousins and cousins is very popular, and even the basic configuration of most families with heads and faces.

The existing custom of "kissing and kissing" can directly collapse.

Su Lu was not ready to raise his arms and call on everyone to have good births and children, and prohibit the marriage of close relatives. He was purely idle, and wanted to move out and tinker with this experiment when he thought about it.

Experimental class, that's the favorite of the students!

That means you don't have to listen to the teacher's chatter, you can go to the lab and have a class.

Su Lu also liked it, but this pea hybridization experiment took too long, and of course he couldn't do it himself.

Su Lu had already thought about it, he first brought out the basic theory, and then vigorously advocated the benefits of cross-breeding based on the theory of genetics, and a project application was done.

In the final analysis, the Great Song Dynasty is still an agricultural civilization, and once it comes to grain production, it is not a matter of minutes to set up a project!

As for the proposal not to marry close relatives, we should not rush it, at least until everyone generally accepts the principles of genetics before we can slowly change people's perceptions.

Su Lu picked up the lamp to write the project proposal, and almost didn't get up the next day.

He rubbed his eyes and went to Zishantang, where he saw Princess Fukang again. She seems to be very interested in Zishantang, and today she grabbed the job of delivering snacks for the second time.

In the face of Princess Fukang, who was about to face the situation of marriage between close relatives, Su Lu thought about it, invited Princess Fukang to come and see the project proposal she wrote, and explained the genetics principles involved to them on the spot.

Zhao Zhongjun is still young in the end, according to the age of later generations, he is also a primary school student. Listening to these genetics principles that can only be involved in high school, I just feel that I am in the clouds, and I can't understand it at all.

However, Wang Yan and Princess Fukang understood a rough idea.

After mastering the basic genetic theory, they started to do the example problems given to them by Su Lu on the spot, and the two of them were quickly immersed in the genetic calculation problems and couldn't extricate themselves, and they didn't even notice that Han Jiang was coming.

Han Jiang frowned when he saw a half-grown girl appear in Zishan Hall. He quickly judged the girl's identity and stepped forward to remind, "I've seen Your Highness." ”

Princess Fukang suddenly came back to her senses.

She has been taught by Queen Cao since she was a child, she writes well and does not say anything, and her arithmetic is not bad.

Princess Fukang knew that Zishantang was not the place she should be, so she hurriedly got up and hurried away. On the way back, she was still worried about the dominant traits and recessive traits that Su Lu said, and decided to start the investigation with double eyelids and single eyelids, and learn from Su Lu to draw a genetic pedigree map of the people around her!

This kind of knowledge was unheard of for her before!

Princess Fukang was in high spirits and instructed her most trusted chamberlain, Liang Huaiji: "You call everyone over in a while, I have something to ask them!" ”

Liang Huaiji also listened to Su Yan's explanation just now, and naturally did as he was told.

Meanwhile.

Zishantang.

After Princess Fukang left, Han Jiang didn't start lecturing immediately, but asked Su Lu what they were doing just now.

Han Jiang asked right in the middle of Su Zhen's heart, he was looking for an opportunity to sell the project proposal to Zhao Zhen, so as to borrow the greenhouse and planting experts in the palace, this kind of research work related to people's livelihood and people's conditions is naturally the best for the state to allocate funds and the state to allocate people.

He has no money, no land, and no one, but he doesn't want to ask for hardship!

Su Lu honestly and unceremoniously explained the principles of genetics to Han Jiang, and began to blow the research significance of this theory according to the content of the project proposal, and finally said to Han Jiang with a shy face: "I think that if the truth can be studied, it will be of great benefit to Jiangshan Sheji, I wonder if Mr. can help present it to the official family?" ”

Han Jiang took the project proposal written by Su Lu and read it.

The project proposal is to be shown to others, and when Su Lu wrote it, he received several successes from himself, and the writing can't be said to be beautiful, at least it can be called neat. And he himself is from a science and engineering background, and he writes things in a clear manner, and every one can be implemented, Han Jiang read it completely smoothly.

Han Jiang originally thought it was ridiculous for the official family to find a kid younger than Zhao Zhonghua to read with him, but after reading this manuscript, he felt that the official family really had a unique vision.

Not to say whether this theory is true or false, just looking at this project proposal is an indescribable enjoyment, there is no half a sentence of redundancy throughout the article, the theory is very clear, the operation method is written carefully but not redundant, even if it is read to illiterate people can follow the operation.

The whole experiment is just planting a few peas and taking a little labor, and it doesn't cost much at all, but if it is done, it will indeed be of great benefit to Jiangshan Sheji!

Based on this alone, Han Jiang knew that the official family would definitely agree to let people try it.

Han Jiang responded: "When I get out of school, I'll go and ask to see the official." Don't run around then, the officials may want to see you. ”
