After Luo Ziling had breakfast in the cafeteria, he didn't go to class with Cao Jianhui and the others.

For Luo Ziling's skipping class, the other three guys didn't feel particularly good, and after they complained a few words, they went to class by themselves.

After Luo Ziling armed himself, he also left the school and joined Luo Yuqing.

Today's Luo Yuqing also covered herself.

Originally, Luo Yuqing never dressed up when she went out, and her plain face was very eye-catching, but when she heard Luo Ziling say during her morning exercise this morning, the people in their bedroom were talking about them, so she also became low-key, and armed herself with scarves, hats, glasses, and other weapons, which almost didn't recognize Luo Ziling.

The forensic laboratory didn't work until nine o'clock, and when the two of them arrived there, it wasn't even nine o'clock.

The two waited stupidly at the door for a while before waiting for the staff to come to work.

Seeing Luo Ziling and Luo Yuqing appear in front of him, Li Muqing couldn't help laughing: "You just need to call and ask about the results, why don't you come here in person?"

"It's better to be solemn," Luo Yuqing smiled a little awkwardly, "Is the result out?"

"I'm going to ask for the results. It should be possible to report the results when I go to work today, I don't know the specifics, I'll ask. Li Muqing asked Luo Ziling and Luo Yuqing to wait, and she went to get the appraisal report.

Luo Ziling and Luo Yuqing were waiting in Li Muqing's office.

Luo Ziling smiled and asked Luo Yuqing, who was a little anxious, "I see you're quite nervous, aren't you?"

"I wondered what I would do if we ruled out the possibility of being a brother and sister. Luo Yuqing smiled, "I didn't come up with an answer, so I was in a hurry." ”

"Didn't you say that if I wasn't your brother, you would chase me and snatch me away from other women?" Luo Ziling said half-seriously and half-jokingly: "It turns out that you just coax me to be happy." ”

"If that's the case, are you really willing to accept my pursuit?" Luo Yuqing looked at Luo Ziling very seriously, "Are you willing to find a girlfriend who is older than you?"

"Most of the girls I know now seem to be older than me. Luo Ziling said with a depressed face: "It may have something to do with the lack of maternal love since childhood." ”

Luo Yuqing didn't know what to say for a while.

At this time, Li Muqing came back in a hurry, holding a report card in her hand.

Luo Yuqing grabbed it very unceremoniously, but after she read the report, she was confused.

"What kind of conclusion is this?" Luo Yuqing pointed to the conclusion at the end of the report and asked Li Muqing: "These letters and numbers, what D8S1179, D21S11, I don't understand at all." ”

Li Muqing patiently explained for them: "These are all DNA point data. In the human body, there are 23 pairs of DNA, half from the father and half from the mother. If it is a father and son or a father and daughter, mother and son, mother and daughter, as long as the three DNA sites are different, the biological relationship can be ruled out. Well, say your results. You were not born to the same mother, and the DNA in your body must be very different. Even if you were born to the same father, there must be some differences in loci because you only share the same genes from your father. The result of this test is that you have multiple loci that are different, but some loci have the same DNA sequence, and the final result is: there is no way to rule out the possibility that you are siblings, but it cannot be confirmed that you are siblings. ”

The test result turned out to be such a vague conclusion, and Luo Ziling and Luo Yuqing were a little disappointed.

"Can you make it clear?" Luo Ziling asked Li Muqing a little depressedly: "You just tell us directly, there is a lot of possibility that we are sisters and brothers." ”

"I'll give you an analogy, if I do a DNA comparison with you, then all the loci should be different, so that the relationship between sister and brother can be completely ruled out, but between you, several of the twenty loci are the same, so there is no way to completely rule out the sibling relationship, but only a few loci are the same, and it is impossible for us to judge that you are a sibling relationship. ”

Seeing that the two of them were still confused after listening to what she said, Li Muqing said again: "Yuqing, let me say this, if you do a paternity test with someone who suspects that it is your father, it should be that most of the DNA loci match, unless there is a variation, if there are more than three loci that do not match, you can rule out the parent-child relationship, if there are only one or two loci that do not match, you have to consider the factor of variation, that is to add locus analysis." Therefore, to determine whether you are the same father, you can only bring your father in or collect samples of his blood, hair, body fluids, etc. for testing. The biggest significance of today's test results is that you can rule out the possibility that you are sisters and brothers, if many loci are not the same, it is definitely not a sister and brother relationship. Let me tell you again what the test results mean, that is, the sibling relationship cannot be ruled out. ”

After saying this, Li Muqing reminded in a low voice: "According to my guess, since the relationship between you and sister and brother cannot be ruled out, it is likely that it is really sister and brother." Of course, this is just my guess, and the accuracy is only fifty percent. The real result is still to get the man you suspect is the common father, and it is possible to be completely sure. ”

Later, she added: "The current paternity test results are like this, if the loci do not match, our report is that paternity can be ruled out 100%, or there is a probability of paternity greater than 99.99%. Why not 100 percent? Because there is a genetic variation, it is not possible to report 100 percent results. Of course, as you know, above 99.99% is 100 percent. ”

After listening to Li Muqing's words, Luo Ziling and Luo Yuqing roughly understood.

If any of them do DNA cooperation with Li Muqing, the result should be able to deny the kinship of the two 100%, and now the test results of the two of them cannot be ruled out--- that is, the possibility of the two sisters and brothers is very high.

The two glanced at each other, and they both saw something strange in each other's eyes.

After thanking them, Luo Yuqing and Luo Ziling left the physical evidence laboratory.

"Don't go to class in the morning, let's find a place to drink tea and chat," Luo Ziling took the initiative to propose.

"Okay," Luo Yuqing readily agreed.

So, the two went to find a teahouse nearby that had already opened, asked for a pot of dragon wells, and some fruit snacks, and sat and chatted.

"Where is your father?" As soon as he sat down, Luo Yuqing asked Luo Ziling, "Can you get his specimen?"

"He's in Tibet!"

By the way, you seem to have said that your father is coming to Yanjing, when will he come?"

"Did I say that?" Luo Ziling looked at Luo Ziling with a puzzled expression.

"It seems to have been said," Luo Yuqing was not very sure.

"It may come," Luo Ziling hesitated, but still nodded, "I just don't know when it will come." ”

"Otherwise, when he comes, you can find a way to get a little specimen, and it doesn't matter if he has hair, saliva, blood, or muscles, or skin. Luo Yuqing looked very anxious, "In that case, we can quickly know the real situation." ”

"Well, I'll figure it out then. ”
