The road from Africa to Europe

Chapter 47 Genetics

Good-looking is very good-looking.

But usually pay more attention to sun protection.

Too little melanin increases the risk of skin cancer.

Of course, she couldn't tell the original owner about this scientific explanation.

Because she couldn't explain clearly what is gene and what is tyrosinase deficiency.

The more you talk, the more knowledge blind spots you bring to the original owner, and the more you can't explain it clearly.

That was digging a hole for herself, and Ling Xiao was bound to start from the beginning. For the original owner, even after Ling Xiao explained, she still couldn't understand.

How should I explain it clearly to the original owner?She thought about it and remembered the research of the false original owner.

"Remember those flowers?" Ling Xiao said, it's easier to understand with examples.

During this time, the original owner was exercising hard.

Try to remember all she can remember.

Research results of false original owners are also included.

As for how to convince the original owner who hates Xibei goods?

It was Ling Xiao who told her that this was the result of Xibei's research after a lot of effort.

If the original owner has mastered its research results, the original owner will be the one who benefits in the end. This can be regarded as a kind of compensation. The original owner likes it very much.

The original owner was studying hard, basically memorizing what Xibeihuo had studied, she nodded.

"Remember, it's grown for several years and the flowers come in many colors," she said.

"Yes, the color of the flower comes from the father and mother."

"It seems so." The original owner scratched his hair.

The male parent refers to the body of the plant that is pollinated.

The female parent is the plant that is pollinated and produces seeds.

What is the principle of this, the original owner has never figured it out.

"You see, the seeds that come out like this will inherit something from the father and mother."

"It's the same as human beings. The offspring all have some similarities with the elders."

"Ah! I see. You mean to say that the sheep's white head is inherited from my parents?" the original owner suddenly had an idea.

She then asked another question, "But, as far as I know, they are not white sheep."

If it had been Baitou, they would not have stayed in Jiangling Pass, they would have arrived at the other courtyard long ago.

"There are things that are inherited all the time that don't show."

This is the so-called recessive inheritance.

"Their descendants will show that their ancestors are different from ordinary people."

As for which offspring will manifest the genetic genes of the ancestors, it is hard to say.

The original owner was a little dazed, she had been bored in the room before, and didn't need to use her brain at all, so she was a little dizzy at the moment.

Why did she know every word Ling Xiao said, but couldn't understand it together?

"Hey! Inbreeding is not conducive to prenatal and postnatal care."

"What did you say?" the original owner said.

She was even more dizzy at the moment, and didn't understand what Ling Xiao said.

"You also remember what the Xibei shopkeeper checked." Ling Xiao said.

She saw that the original owner didn't understand at all, so she said that the original owner also had some memories.

The original owner thought about it for a while, and finally pulled out some Xibei goods from her memory. After looking at it, she didn't understand.

Ling Xiao explained to her that people in this world also like to marry close relatives. They like to find a niece from their natal family for their sons, or marry their daughters back to their natal families after they get married.

A large part of the reason for the appearance of white-headed sheep is the result of inbreeding, which is the result of scientific research in later generations.

The reason is a genetic defect, if the husband and wife are just one child.

The child is likely to be dominantly inherited.

There is also the possibility of recessive inheritance.

But both carry it.

Their children will be highly dominant.

It is several times higher than the children of non-consanguineous marriages.

This is also the reason why close relatives are prohibited from marrying in the Marriage Law in later generations.

As for the genetic defect, Ling Xiao knew that even in modern times, it still cannot be solved.

Because the development of science and technology has not advanced to the step of modifying genes.

After listening to the original owner, he pondered for a long time before realizing something.

"Is that the reason?" the original owner said.

"You know there's always something alike between relatives, it's genetics."

"It's like the same type of flower, even though the color is different, but the flower shape is still the same."

"I understand." The original owner suddenly laughed.

"If it's not a family."

"It's like a flower, but the shape of the flower is different."

When Ling Xiao heard this, he couldn't say anything for a while.

In fact, between humans and flowers, forget it, let’s explain it this way first.

"You also know that the Xiao family has white-headed sheep for generations, which proves that it is a family." Ling Xiao said.

As a person who comes from the era of information explosion in later generations, I know a lot of things on the Internet.

Ling Xiao knows that some unbelievable things will happen to normal human beings in the process of reproduction.

For example, there will be an extra tail coming out of the newborn's buttocks, and that tail is alive.

In modern society, this is not a big deal at all, as long as the doctor performs an operation on the newborn to remove the tail.

Modern people who have received relatively complete education basically know the so-called tail, which is just an atavistic phenomenon.

Because every fetus has a tail when it is in the mother's womb, but the tail degenerates during the growth process.

In fact, even if it is degenerated, at the bottom of the tail vertebrae, there are tail bones.

It's small, but you can still feel it with your hands.

It can definitely be felt.

If you accidentally land on your hips.

It will hurt.

It is possible that the tailbone was broken.

There are very few children who don't know why.

At birth, the tail is still intact.

Just like being born with a tail, a small operation is enough.

However, in the ancient times when the reason was unknown, this child would have been a monster in the eyes of the ancients, and his fate would definitely not be good.

If you think about it this way, a person with a white head is a trivial matter.

When the original owner heard that there was a tail, he thought he heard it wrong.

She couldn't imagine what the tail was all about.

But reach out and try the coccyx part.

It really is.

This discovery surprised her.

"It turns out that the human body still has so many mysteries."

The original owner's eyes widened. She had an idea and wanted to go her own way.

"Ling Xiao, if you compare yourself with unlucky children, you are already very happy." Ling Xiao sighed

Happiness is all about comparison, without comparison, there is no feeling.

For example, a person riding a donkey must be compared with a person riding a tall horse.

Then it must be better than riding a horse in every way.

Definitely feel bad about living.

But if you change to a broad-minded person.

It feels like the comparison doesn't matter at all.

There are also people who change the control group and compare it with people who can only walk.

The sense of happiness will definitely soar directly, and people will live happily.

And Ling Xiao just wanted to let the original owner feel that she also had very happy moments.

If you always stare at yourself and have nothing, you will only live in a very unhappy life, and you will always be unhappy.

Ling Xiao cherishes the hope that the original owner can come out of the horns and live for himself.

The original owner was living for the second time, and the idea of ​​wanting to change the way of living spontaneously arose.

As she worked hard on herself, she felt empowered.

The negative emotions that have been weighing heavily on my heart.

It turned out to be a little loose, a little relaxed.

Naturally, I want to practice hard.

Every time she finishes her practice.

Feeling sleepy and tired.

I just want to sleep well and have no time to think about it.

Under such circumstances, the original owner gradually mastered his body and practiced his skills.

"Now that you have improved a lot, it will be faster and easier to kill a few smelly rocks with your own hands." Ling Xiao finally spoke.

Hearing Ling Xiao's words, the original host shuddered, and the scene of killing Smelly Yan reappeared.

It was not very good news for her, and she really wanted to quit.

But Ling Xiao said: "Don't expect me to fight."

The original owner raised his head.

　In order to maintain the pure bloodlines of the ancient Egyptian royal family, the pharaoh's heirs were the children born after close relatives married.The ancient Egyptian pharaoh Akhenaten looked like an alien.

　　The child with a long tail, the deepest memory in fleeting years is the end of "One Hundred Years of Solitude", where the child was carried away by ants.
