PROLOGUE
The Question
Professor Shunya Raman was accustomed to difficult
questions.
Students asked him why stars exploded, whether
plants could feel pain, and if human beings might one day live on Mars. He
never laughed at a question, however strange it sounded. To him, every question
was a door, and curiosity was the key.
But one rainy afternoon, a question arrived that
made him remove his spectacles and read the message twice.
“Is the X chromosome found in a female the same as
the X chromosome found in a male?”
The message had been sent by Dr Tara Kaul, a
celebrated novelist and one of Professor Raman’s sharpest critics.
The professor smiled.
“The X chromosome is the same kind of chromosome in
both,” he dictated into his recorder. “A female usually has two X chromosomes,
while a male usually has one X and one Y. A son receives his X from his mother and his Y from his
father. A daughter receives one X from each parent.”
He paused before adding, “But why does a novelist
need to know this?”
Her reply arrived almost immediately.
“Because I am writing science fiction.”
That explanation should have satisfied him.
It did not.
CHAPTER ONE
The Locked Laboratory
Twelve-year-old Aadi Raman knew three important
things about his grandfather.
First, Professor Raman added cinnamon to almost
everything he ate.
Second, he never locked his study.
Third, whenever he said, “There is absolutely
nothing to worry about,” there was always something to worry about.
On the evening of the mysterious message, the
professor locked both his study and the underground laboratory.
“There is absolutely nothing to worry about,” he
told Aadi.
Aadi exchanged a glance with his best friend, Meher
Aziz.
They had been building a model volcano in the
professor’s kitchen. Their volcano had failed to erupt, but the professor’s
behaviour was far more interesting.
“Something is wrong,” Meher whispered.
“Definitely,” Aadi replied. “He forgot the
cinnamon.”
Later that night, a flash of blue light shone
beneath the laboratory door.
Aadi and Meher crept downstairs. Through the glass
panel, they saw the professor standing beside a transparent chamber. Inside it
floated thousands of glowing threads.
Some shone silver. Others flickered blue.
On the central screen appeared two enormous letters:
X — ACTIVE
Y — ACTIVE
Then a third message began flashing:
PROJECT VEIL INITIATED
Before Aadi could read more, an alarm screamed.
The blue lights vanished.
When the laboratory door opened, Professor Raman
stood before them with a face as pale as moonlight.
“The formula has been stolen,” he said.
CHAPTER TWO
The Chromosome Library
The professor brought Aadi and Meher into the
laboratory and switched on the Helix Projector.
Two twisting ladders of light rose into the air.
“Inside nearly every cell,” he explained, “is a
library of biological instructions. Chromosomes are like volumes in that
library. They carry genes, and genes help guide how living bodies grow and
function.”
A glowing X appeared.
“The X chromosome carries many important genes. It
is not a ‘female chromosome’ belonging only to girls. Boys usually have an X
chromosome too.”
A smaller Y appeared beside it.
“The egg always contributes an X. The sperm may
contribute an X or a Y. An X-carrying sperm may lead to an XX child; a
Y-carrying sperm may lead to an XY child.”
“So, fathers determine whether the embryo is usually
XX or XY?” Aadi asked.
“In that limited biological sense, yes,” said the
professor. “But inheritance is far more complex than two letters. Human beings
are never merely Xs and Ys.”
Meher pointed towards the flashing words PROJECT
VEIL.
“What was stolen?”
The professor hesitated.
“An imaginary idea that someone has turned into a
dangerous invention.”
CHAPTER THREE
Formula XY-12
Years earlier, Professor Raman had imagined a
microscopic molecular covering—a “chromosomal veil” capable of temporarily
hiding a selected chromosome from an artificial detection system.
It was only a computer model. It had never been
intended for use in a human body.
But someone had secretly developed it.
The stolen compound was called Formula XY-12.
According to its creator’s notes, an unimaginably
small quantity could place a temporary veil around X-carrying reproductive
cells. The effect would remain strong for several weeks before gradually
fading.
“It doesn’t destroy the X chromosome,” Professor
Raman explained. “It merely prevents the fictional cellular machinery in our
story from recognising it properly.”
“If the X-carrying cells are hidden,” Meher said
slowly, “wouldn’t the Y-carrying cells have a greater chance of succeeding?”
“That is the theory.”
“But why would anyone want that?”
The professor looked towards the rain striking the
laboratory windows.
“Because there are people who still believe that one
kind of child is more valuable than another.”
CHAPTER FOUR
The Woman in the Silver Mask
The laboratory cameras had captured only four
seconds of the thief.
She wore a silver mask and a black coat. On her
wrist was the symbol of a coiled serpent surrounding the letters N.G.
“NovaGenesis,” said Professor Raman. “A private
company claiming it can design the future of humanity.”
NovaGenesis was led by Dr Viraaj Kross, a wealthy
geneticist who promised parents healthier, stronger and more intelligent
children. Behind the bright advertisements, however, rumours spoke of secret
experiments.
Aadi enlarged the security image.
“There’s something reflected in her mask.”
Meher studied it. “It looks like a clock tower.”
There was only one such tower in the city—the
abandoned Meridian Observatory.
That night, against the professor’s instructions,
Aadi and Meher cycled towards it.
CHAPTER FIVE
The Observatory
Inside the ruined observatory, they found a hidden
lift descending deep below the ground.
The underground rooms were clean, bright and
frighteningly silent. Rows of artificial cells floated inside glass containers.
On a giant screen, a countdown had begun:
GLOBAL TRIAL: 59 DAYS, 23 HOURS, 41 MINUTES
A map showed twelve cities marked in red.
Beside it appeared the slogan:
LET CHANCE END.
LET CHOICE BEGIN.
Meher’s face tightened.
“They’re going to test the formula on people.”
A voice answered from the darkness.
“Not people. Volunteers.”
Dr Tara Kaul—the professor’s literary critic—stepped
into the light.
“You sent the question,” Aadi said.
“Yes.”
“You stole the formula?”
“No,” Tara replied. “I asked the question because
somebody asked me to write a convincing story about it. They wanted fiction
that could make a dangerous idea sound beautiful.”
She placed a data crystal in Meher’s hand.
“I refused. Now NovaGenesis is hunting me too.”
CHAPTER SIX
A Future Without Daughters
The data crystal contained a simulation.
At first, it showed families celebrating the birth
of sons. Then the years moved forward.
Schools grew emptier on one side of their
classrooms. Communities changed. Millions of boys grew into men in a world with
far fewer women. Loneliness increased. Families struggled. Criminal networks
began controlling marriages and migration.
The simulation moved forward to another generation.
A warning covered the screen:
GENETIC DIVERSITY DECLINING
SOCIAL STABILITY CRITICAL
POPULATION FUTURE UNCERTAIN
“A choice made by one family may appear private,”
Tara said, “but repeated millions of times, it can reshape the world.”
Meher stared at the screen.
“My parents never knew whether I would be a boy or a
girl. They only hoped I would be healthy.”
“And noisy,” Aadi added.
“They got both,” she replied.
For the first time that night, everyone laughed.
Then the underground alarm began to howl.
CHAPTER SEVEN
The Man Who Wanted Certainty
Dr Viraaj Kross appeared on every screen.
He had silver hair, a calm voice and eyes that never
seemed to blink.
“Professor Raman trusted chance,” he announced. “I
trust human choice.”
Kross believed uncertainty was a disease. He wanted
parents to select not only whether a child would be male or female, but
eventually height, appearance, talents and personality.
“No more accidents of birth,” he declared. “No more
imperfect futures.”
Aadi stepped towards the camera.
“People aren’t products.”
“Everything can be improved,” Kross replied.
“Who decides what ‘improved’ means?” Meher asked.
“You?”
For a moment, Kross’s smile disappeared.
The doors locked around them.
Gas began filling the corridor.
CHAPTER EIGHT
Barr, the Sleeping X
Tara led them through a maintenance tunnel into a
chamber containing the central computer.
Its name was BARR.
“Named after the Barr body?” Meher asked.
Professor Raman had explained that in many XX cells,
one X chromosome becomes largely inactive. It folds into a compact form,
helping balance the activity of many X-linked genes.
“Exactly,” Tara replied. “Kross misunderstood
nature. He thought that because a cell can quiet much of one X chromosome,
science should be able to silence any chromosome whenever it wishes.”
BARR, however, had learned more than Kross expected.
It spoke through the laboratory speakers.
“A chromosome is not a switch. A child is not a
calculation. Biological systems contain exceptions, variations and
consequences.”
“You sound like Professor Raman,” Aadi said.
“I was trained using his lectures.”
“Can you stop the trial?”
“Only if you reach the transmission tower before the
countdown ends.”
CHAPTER NINE
The Weakening Veil
The group learned that Formula XY-12 had a flaw.
The veil did not disappear at once. It weakened
unevenly.
Some cells remained masked. Others became visible
again. In computer simulations, the result was not certainty but chaos. The
compound could disrupt ordinary cellular signals and produce unpredictable
consequences.
Kross had hidden these results from his investors.
“He never created control,” Meher realised. “He
created another kind of uncertainty.”
“And a more dangerous one,” said Tara.
To stop the trial, they needed three security keys:
The scientist’s key—held by Professor Raman.
The storyteller’s key—hidden in Tara’s data crystal.
The future’s key—a new command that could be written
only by someone under the age of sixteen.
“Why a child?” Aadi asked.
“Because Kross wanted to claim that everything he
did was for future generations,” Tara replied. “His own security system
requires the future to approve.”
Meher smiled.
“Then the future says no.”
CHAPTER TEN
The Choice Chamber
At the top of the tower, Aadi and Meher found the
transmission controls.
Kross was waiting.
He offered them a bargain.
“With this technology,” he said, “we could prevent
terrible illnesses. We could remove suffering.”
“Preventing disease is not the same as deciding
which children deserve to exist,” Meher replied.
“Every invention can be used well or badly,” Kross
argued.
“Then why did you hide the failed trials?” Aadi
asked.
Kross said nothing.
Aadi inserted the scientist’s key.
Tara inserted the storyteller’s key.
Meher typed the future’s command:
NO CHILD SHALL BE MEASURED BEFORE BEING LOVED.
The system requested confirmation.
Kross lunged towards the controls.
Aadi pressed ENTER.
CHAPTER ELEVEN
The Unmasking
Across the laboratory, containers opened and
released harmless clouds of violet vapour. The remaining formula changed
colour, allowing investigators to locate every stored sample.
BARR transmitted the secret trial records to
independent scientists and public authorities.
The global countdown stopped at seven seconds.
Kross stared at the blank screens.
“You have destroyed humanity’s chance to control its
future,” he said.
Professor Raman, who had finally reached the tower
with the authorities, answered him.
“No. They have protected humanity’s right to have a
future that belongs to everyone.”
Kross and his associates were arrested. NovaGenesis
was closed, and its legitimate research was transferred to organisations
governed by strict ethical oversight.
Tara’s role was publicly revealed. Some called her a
hero.
She disagreed.
“I merely asked why,” she said. “The children were
brave enough to ask whether we should.”
CHAPTER TWELVE
The Story Begins
Several months later, Aadi and Meher sat in their
classroom as Professor Raman gave a special science talk.
He held up two books.
One had X printed on its cover. The other had Y.
“The X chromosome found in a male is the same kind
of chromosome as an X found in a female,” he explained. “But chromosomes do not
write the entire story of a person. Biology gives us beginnings, possibilities
and variations. Life adds experience, relationships, choices and dreams.”
At the back of the room, Tara was writing in a
notebook.
“What is your new novel about?” Meher asked.
“A scientist who tries to mask a chromosome,” Tara
replied.
Aadi groaned. “After everything that happened?”
“Yes, but the scientist discovers that the most
dangerous thing being masked was not the chromosome.”
“What was it?”
“The truth.”
She closed her notebook. On its cover was a title:
THE VEILED CHROMOSOME
A Story by Sham Misri
Outside, the final bell rang. Girls and boys poured
into the playground together—arguing, laughing, racing and dreaming.
Each carried chromosomes within them.
But none could be reduced to a letter.
EPILOGUE
THE PROFESSOR’S NOTE
The chromosome-masking compound described in this
story is entirely imaginary. No real drug or chemotherapy can safely and
temporarily hide a man’s X chromosome to guarantee the conception of a male
child.
The science-fiction idea gives us a deeper question
to consider:
If human beings gained the power to control every
feature of future children, should they use it?
Science can tell us what may become possible.
Wisdom, compassion and ethics help us decide what should be done.
A child is not an order placed in advance.
A child is a new story entering the world.
