"Meat?"
Mao Lilan and Suzuki Sonoko looked at each other, but didn't take it seriously.
It is normal for young children to not recognize all the words they use in daily life and have words they don’t understand.
"Speaking of which..."
Conan finally finished eating the macarons and said while licking his fingers:
"Ms. Xia Mei's eyes are gray."
"Yes, my mother and grandmother are the same color."
Kosaka Natsumi gently leaned down so that Conan could see more clearly:
“It must be hereditary.”
"Ms. Qinglan's eyes are also gray!"
Reminded, Mao Lilan asked:
"Do all people from Country Z have grey eyes?"
"Yeah...right."
Pu Siqinglan nodded, her tone somewhat uncertain.
at this time...
Sakaki Makoto began to lose control of his facial muscles again.
He looked at Pu Siqinglan with a strange expression, wanting to tell her...
Stop it.
From a genetic perspective, eye color is determined by the iris.
The color of the iris is determined by the amount of melanin in the body.
Generally speaking, white people have less melanin deposits in their bodies, so their skin appears whiter and more pink than other races.
The same goes for the iris.
The irises of East Asians are dark brown, those of Western Europeans are light blue, and some people in Northern Europe even have green eyes.
Whether gray or green, they are all derived from the variation of blue iris genes, and the proportion of gray eyes is less than one in one hundred thousand.
It’s not that there are no gray eyes in Country Z. Apart from special cases of mutation, people with gray eyes generally have Western ancestry.
"Did you find out?"
Miss Miyano said in a voice that only the two of them could hear:
"Pusi Qinglan is not from Country Z."
"Huh?"
Surprised, Sakaki Makoto asked in astonishment:
"How do you know that?"
Although he knew from the beginning that Pu Siqinglan was not from Country Z, but...
It is not easy for Miss Miyano to distinguish the other party's identity.
"First of all, there is no surname called Pu Si in Country Z."
Sitting in a dignified posture, she appeared very calm:
"When I was studying in the United States, I met a professor who specialized in the history of Country Z. Secondly..."
"This professor has a friend named Hans Eiberg who is in charge of genetics."
"He had published a paper on regional differences in iris color and learned that..."
Picking up the teacup, Miss Miyano took a sip of tea and said softly:
"The gene for brown irises is dominant and arose millions of years ago."
"The mutant gene OCA2, which changes the iris to blue, appeared very late, around 10,000 BC, and was mainly concentrated in Northern and Eastern Europe, most of which were Estonians."
It's really amazing...
She is indeed a genius girl.
Makoto Sakaki was extremely happy about Miss Miyano's erudition.
However...
Miss Miyano hasn't finished her words yet:
"99% of Estonians have blue eyes, of which 75% are Germans and 50% are Russians. Among these 50%..."
"20% of the irises are sky blue, and 30% are gray-blue."
"The reason for the gray-blue iris is that the surface of the eye is covered with a layer of protein. Over time, the protein is gradually oxidized and turns into a yellow substance. When observed through this layer of yellow substance, it looks like gray, but..."
As she spoke, she frowned:
"The pure gray color of Miss Xia Mei and Pu Siqinglan should be a genetic mutation, which is very rare."
When it comes to the biological field, it’s Miss Miyano’s special show.
In order to develop APTX4869, she approached many aspects, including genetic genetics.
For example, some people live long lives. Is it because of their lifestyle habits or their body structure that makes them live long?
Science is used to verify these things.
"You are right."
Sakaki Makoto nodded:
"Pusi Qinglan is definitely not from Country Z."
"But in the northwest and northeast regions of Country Z, there are still people with gray eyes."
"Um..."
Miss Miyano was stunned for a moment, then reacted:
“Could it be because of the nomadic invasion of Europe more than 700 years ago?”
"right."
Taking out his cigarette box, Sakaki was about to light one, but considering that no one in the room smoked, he reluctantly put the cigarette box back in his pocket.
"Between 1237 and 1242 AD, the nomadic peoples who invaded Europe from the southeast greatly influenced and changed the Russian race."
"Because brown irises are a dominant gene, many children with brown eyes are born, and they all have East Asian features."
"And this population proportion is about 25%."
At this point in the discussion, Makoto Sakaki had already exchanged all the information he knew with Miss Miyano.
They all came to the same conclusion.
This woman named Pu Siqinglan...
Most likely Russian.
Of course, the decisive evidence was what she said next.
"In Country Z, my name is pronounced Qinglan. Lan is pronounced the same as your name, Miss Maori."
Pu Siqinglan smiled and showed her "erudition" to Mao Lilan and Suzuki Sonoko:
"As for Miss Sonoko's name, it is pronounced as..."
