Harry Potter and the Great Old Ones

Chapter 20: Speculations on the Genetic Principles of the Spiritual Dimension of Wizards

The sliding door to the cubicle opened, and the youngest child with fiery red hair walked in.

"Can I sit here?" he asked cautiously, pointing to the empty seat opposite Harry. "All the other seats are full."

"Okay, please sit down."

Ron sat down. Without his two mischievous twins by his side, the young Ron was still a little reserved when facing the legendary Harry Potter.

He glanced at Harry, then at Tyrell sitting next to Harry reading a book, before immediately turning his gaze to the car window, pretending not to see Harry.

Harry noticed a very noticeable stain on the tip of Ron's nose, like a mixture of plaster and cheese that had dried out. Having seen Tierra's always neat and meticulous appearance, the stain on Ron's nose seemed particularly jarring.

Harry almost wanted to hang him up with his bare hands.

"Hey, Ron."

After saying goodbye to their mother and younger sister, the Weasley twins found Ron in the private room.

"Listen, we want to go to the middle carriage now. I heard Jordan got his hands on a huge bag spider!"

"Oh," Ron muttered, clutching the hem of his shirt tightly with both hands, looking a little nervous.

“Harry, and Tyella!” said the other of the twins. “We haven’t introduced ourselves yet, have we? I’m Fred, this is George, and this is our little brother, Ron Weasley. See you in a bit.”

After saying that, the Weasley twins ran off in the train aisle in a flurry of activity.

"Goodbye," Harry and Ron replied politely, while Tyella sighed as she watched the twins leave.

A tragedy is the destruction of something beautiful to the viewer.

Tierra thought to herself.

Then Tierra gently closed *Fantastic Beasts and Where to Find Them*.

“Hello, my name is Tierra Witch.” Tierra said, extending her hand to Ron. “From now on, we’ll be classmates.”

“Uh… um, my name is Ronald Weasley! You can call me Ron.” Ron also extended his hand.

"Do you...do you remember what the mysterious man looked like?" After Tiera broke the awkward silence, Ron finally mustered the courage to ask the question he most wanted to ask.

“I don’t remember,” Harry replied. If he did remember, he wouldn’t have gone eleven years old before finding out he was a wizard.

"You don't remember anything at all?" Ron asked eagerly.

"Hmm... I only remember there was a lot of green light, I don't remember anything else."

"Oh dear!" Ron stared at Harry's forehead for a long time before suddenly realizing that it seemed to be a very impolite thing to do, and quickly turned his head to look out the window.

"Is your whole family wizards?" Harry asked after he realized that he and Ron were both interested in each other.

“Oh yes, I think so,” Ron said. “I think my mother has a distant cousin who is an accountant, but we never talk about him.”

“An accountant?” Tierra keenly caught this.

This is an instinctive intuition, like that of a living being.

"So, one of your mother's relatives isn't a wizard?" Tierra asked.

"Hmm...that seems to be the case, that's what they said." Ron scratched his head.

"Is your relative the accountant, and both parents are wizards? Or is one a wizard and the other a Muggle? What about your relative's paternal grandparents? Were they also wizards? Or do they have Muggle blood? What about your relative's maternal grandparents? What's their situation?"

"Uh... to be honest, I don't know the specifics... they're very distant relatives, we hardly ever have any contact..." Tierra was a little dizzy from the questions, wondering why she was asking such trivial things.

He could only silently label Tiera as a weirdo in his heart.

“Really…” Tiera looked a little disappointed. “That’s a shame.”

To be honest, Tierra was very curious about the emergence of wizards. Although Merlin's notes and the Necronomicon explained the origin of magic as a three-dimensional theory of matter, spirit, and mind.

However, the existence of the Squib and the sudden birth of a wizard descendant from a Muggle with no wizarding blood, coupled with the fact that the Muggle's genetic traits were almost identical to those of pure-blood wizards, made Tiera keenly aware of a genetic phenomenon.

Tierra speculated that the existence of Squibs was likely a form of genetic masking.

According to what Tierra knew from her previous life about Rowling's additional information about Harry Potter, there were only about 8,000 wizards in the entire UK. In addition, some wizards have always adhered to the pure-blood theory, so inbreeding among wizards should be quite common.

Considering Neville's experience—that he never displayed obvious magical talent from a young age until his uncle accidentally threw him down the stairs, and the existence of the Obscurus—if magical talent, or spiritual dimension coordinates, is indeed determined by genes, then the expression of these genes is heavily influenced by the environment, suggesting that they are likely quantitative trait genes.

From a genetic perspective, consanguineous marriage leads to an increase in homozygous or identical genes, which helps accumulate quantitative genes. Just like in hybrid rice, where the desired quantitative traits are selected, it often requires several generations of self-pollination.

This accumulation of quantitative genes eventually leads to the overexpression of a certain type of quantitative gene, which masks or inhibits the expression of its alleles.

This may be the reason why duds occur.

Squibs are also three-dimensional beings, capable of seeing Dementors of spiritual beings. And if we assume that having coordinates in the spiritual dimension is the result of gene expression, then the reasonable explanation for Squibs is that the gene responsible for spiritual dimension coordinates is overexpressed, thus completely obscuring the gene that is equivalent to it and can express the trait of using magic.

Hmm... Tiera nodded silently. All of this was just speculation, lacking evidence.

If Ron's distant relative's parents were both pure-blood wizards and there was no record of marriage between his ancestors and Muggles, that might be strong evidence for his conjecture.

However, the final confirmation still requires rigorous experiments to verify this hypothesis.

Unfortunately, he had ideas but lacked the necessary experimental facilities and personnel.

Otherwise, if this experiment could be done, it would at least be a Nobel Prize-level discovery.

This reveals another possible branch of human evolution.

Tiera suddenly realized that the wizarding world was a vast subject, not limited to genetics, but also including the physical and chemical principles of magic, transfiguration, and the biological principles of the Animagus.

Furthermore, research on wizarding psychology, social structure, and Gringotts' financial system alone can provide a large number of grammar researchers with numerous research grants and funding opportunities.

Hmm... let's not do too much research for now.

Although he was in the magical world of Harry Potter.

This seemingly simple and orderly magical world on Earth occupies only a tiny, insignificant part of the entire chaotic universe.

Most of the universe outside of Earth is governed by crazy and chaotic rules.

This could lead to a maddening danger in the knowledge that corresponds to these universal laws.

But this is not the reason why Tiera stopped here.

Technology is the primary productive force.

This is the eternal truth.

Just look at the wizards of this world.

The long-term stagnation and self-imposed isolation in the study of magic have gradually transformed these wizards, who once created countless glorious legends, from gods and legends revered in ancient times into pitiful creatures who can only live in the wilderness now.

Let me explain this to those of you who aren't biology majors.

Quantitative trait genes are traits that are controlled by two or more alleles.

Its main characteristics are as follows:
① Individual differences are difficult to describe and require measurement;
② Within a population, variation is continuous;
③ Quantitative traits are often controlled by multiple genes;
④ Quantitative traits are sensitive to environmental influences.

Most traits in an organism are controlled by a number of genes. For example, the color of wildflowers: the offspring of a cross between a red flower and a white flower do not strictly follow Mendel's laws of inheritance. In addition to white and red flowers similar to their parents, there will also be pink and light red flowers of varying degrees and quantities.

The hair loss gene in humans is also controlled by quantitative trait genes, and individuals who carry the hair loss gene are easily affected by the external environment.

For example, high-oil and high-salt foods, staying up late, irregular lifestyle, and even the climate.
