TV series " Sauvignon Blanc " is currently on the air.
Recently, the topic " Tu Shanjing's blood test for relatives and the police's popular science " has become the second most searched topic.
On the evening of July 9, the official WeChat account of the Public Security Bureau of the Ministry of Public Security @中国PoliceOnline mentioned a plot in the play about a blood test.
I heard that Tu Shanjing is taking a blood test to test his identity. No need to doubt it. This child looks nothing like you.
Is Tushan Jing’s blood test method real? Many friends think that if the father and son are asked to do a DNA test, the result will be: "He is the biological father" or "Not the biological father." In fact,
is not like this. Even if is a known paternity test, the result is only a probability. The test of two relatives is called a "double" test. Even if it is the biological father, it only produces a "likelihood rate".
If it is a father and son plus a mother, or another child, the likelihood rate produced by the "triplet" test will be higher than that produced by the dyad. can confirm that he is the biological father only if there are enough genetic loci tested, the likelihood rate is high enough, and reaches a certain standard.
@China Police Online also called actor Deng Wei, who plays Tu Shanjing, online: "Have you learned it?"
That night, Deng Wei responded positively: "I have learned , call Tu Shanjing immediately! "
Netizen comments: knowledge has increased!
luv_sugar: Thank you, policeman, for your popular science! Tushan Jing is pure and innocent!
Bingbao1027: I learned it, thank you to the police uncle for popularizing the science!
You always like d: That’s it. I think most people like me are hearing about it for the first time.
Is the famous scene in the TV series "blood test" really accurate?
In many costume dramas, there will be plots of "blood test". Even those who have never seen it remember this sentence: Those whose blood fuses are relatives.
But in fact, identifies relatives by blood type rather than DNA. The "compatibility" may only be because the blood types are the same, and it has nothing to do with whether they are biological children. After all, there are only four common blood types in . If blood compatibility is used to test, there may be only four major families in the world.
