Chapter 840 The Tong Family Has a Genetic History

Gu Jin lowered his eyes, wondering what he was thinking. It took him a while before he said, "Aunt Tong, I have a question. It may involve family privacy."

Tong Wan regarded Gu Jin as her daughter-in-law and liked her very much. She always spoke softly to her: "It doesn't matter, we are all a family. If you have any questions, just ask."

Gu Jinqing said "hmm" and said, "You knew you were having a daughter before your child was born. Did you do a prenatal gender test in advance?"

In order to prevent families that favor boys over girls from aborting girls in order to have boys, China generally does not allow prenatal gender testing.

But wealthy families are somewhat privileged, and there are ways to know the gender of their children in advance.

Of course, there are also special circumstances where the hospital will allow gender identification.

For example, if there is a genetic disease in the family, and the disease-causing gene is on the sex chromosomes, it is often called a sex-linked genetic disease.

Tong Wan nodded. She was afraid that Gu Yang and Gu Jin would misunderstand, so she explained: "I did a gender test at the beginning. It was part of the prenatal examination.

Our family does not value boys over girls, and gender identification is not done to distinguish between men and women. "

Gu Yang also reacted, "Is it because there is a hereditary disease in the family?"

Speaking of which, her hemophilia is also a sex-linked genetic disease.

Neither the Gu family nor the Ruan family have a history of hemophilia.

The Gu family had never suspected that Gu Yang was not their biological child, so after learning that she had hemophilia, they just regarded it as bad luck and a very unlikely genetic mutation.

After all, Ruan Xueling is engaged in jewelry design. Some jewelry may contain radioactive radiation, and radioactive radiation may cause genetic mutations in babies.

Later, after learning that she was not her biological child, the Gu family also helped her find her biological parents.

Hemophilia is a hereditary disease, so when looking for biological parents, they focus on hemophilia families in Jincheng and nearby cities.

But in the end, I couldn't find it, so I had to give up.

Tong Wan said: "The Xiao family has no history of hereditary disease. However, my natal family, the Tong family, has a history of hereditary disease. I may carry the disease-causing gene, so I need prenatal diagnosis."

Not only this child, but also had prenatal diagnosis before giving birth to Yize. Just to rule out genetic diseases.

I don’t want my child to suffer from illness as soon as she is born. I want her to grow up healthy. "

In that case, Tong Wan had undergone prenatal diagnosis and it was diagnosed that the fetus in her belly was not sick, so she continued the pregnancy.

Gu Yang was moved by this maternal love: "Aunt Tongwan is a good mother."

Gu Jin also nodded and did not ask what the specific genetic disease of the Tong family was.

After all, this is a family secret, and it is not easy for Tong Wan to reveal something.

The information obtained was enough to make Gu Jin give up the absurd ideas he had just raised.

It would be rude to ask any further.

Although she doesn't like worldliness, she still has some sense of proportion.

Tong Wan left Gu Yang and Gu Jin to have dinner at Xiao's house, and then asked Xiao Yize to drive them back to school.

There are self-study classes in the evening.

Feng Jue had been left out all day, and he had to cross the entire campus to pick Gu Yang up to the classroom, so he estimated the time and rode a shared electric donkey to wait for Gu Yang downstairs in Gu Yang's dormitory.

Gu Yang didn't know whether to laugh or cry, but seeing the stubbornness on his face, he could only let him go.

Feng Jue grabbed Gu Yang's hand and put it on his waist, letting her hold him. Only then was he satisfied, and he did not forget to cast a provocative look at Gu Jin.
