The doctor adjusted the glasses on the bridge of his nose and said very rigorously Underground Passage: "According to medical science, only 99.9999% of the time it is possible to completely confirm that there is a father-son relationship."
Cheng Haoming was struck by lightning. "You mean... the child is not mine?"
"Impossible!"
Madam Cheng immediately retorted.
"This child's DNA is so similar to my son's, reaching 95%. How could it not be a parent-child relationship?"
"And the child was conceived under my eyes. I watched my daughter-in-law's belly grow little by little. How could it not be my grandson?"
"You must have made a mistake. Think about it again and test it carefully."
The doctor had seen this kind of situation many times and persuaded her without changing his expression, "Madam, please be quiet and listen to me."
"When we test DNA, the most important thing is to compare their positions in the arrangement. Generally, all 21 positions are the same, so that we can completely confirm that they are father and son. But your son and your grandson only have 20 positions in common, and one is different, so we cannot be sure that they are the biological father and son."
"What's the same but different, isn't it just one difference? Maybe there is some genetic mutation? How can you say that they are not father and son?"
Madam Cheng feels that this doctor is just making things up out of thin air and looking for trouble.
The doctor nodded, agreeing with part of her point.
"A genetic mutation from the mother's side cannot be ruled out at all."
"So, my suggestion is, if you must find out clearly, please provide the mother's testing materials."
Madam Cheng snorted coldly, "Then let's go back and get it now."
She didn't believe it. The child was conceived under her nose, so there could be something wrong.
Cheng Haoming still didn't move: Doctor, apart from the genetic mutation on the mother's side, what other conditions can cause this phenomenon? "
The doctor hesitated for a moment and chose to tell the truth.
"The only remaining reason is that the father of this child is related to you by blood, and the relationship is very close. Otherwise, the similarity would not be so high."
Cheng Haoming's heart suddenly sank to the bottom, and he asked with trembling lips, "How close... how close do you need to be?" "
"For example, your brother, or..."
Cheng Haoming grabbed his hand nervously. "Or what?"
The doctor didn't care and looked at him with some pity. "Or, your immediate family members."
Cheng Haoming turned pale suddenly, took two steps back involuntarily, and leaned against the wall. "You mean... my father, right?"
Doctor: "I don't rule out grandpa or your son."
His grandfather died long ago, and he was only twenty-five years old, so he had no son at all...
Cheng Haoming's whole mind buzzed, as if a firecracker had been exploded.
His body staggered, unable to stand still, and finally he slid to the ground with his back against the wall.
"Impossible... impossible..."
"How is this possible... how is this possible..."
His father... this is a huge joke.
"Haoming, what on earth are you talking about? Why can't I understand?"
Madam Cheng still haven't figured out what's going on.
She just wanted to go home and see the child, and didn't really listen to the doctor's words clearly.
The doctor glanced at the woman who couldn't even understand her words, but didn't say anything. He looked at Cheng Haoming: "Mr. Cheng, do you still want to check?"
Cheng Haoming had a livid face, holding on to the wall, and struggled to get up from the ground, with cruel intent in his eyes. "Check!"
He must find out everything.
