Wang Baoqiang paternity test result picture tells
Wang Baoqiang's public divorce caused an uproar on the Internet, and Weibo became the main battlefield for the dissemination of news. For a while, the news was all over the place, and under the premise that the parties did not respond further, there were obviously many rumors.
Because Wang Baoqiang claimed that his wife had cheated in marriage, there were so-called "whether the child is his own" doubts, and even suspected "paternity test" reports.
Rumor Review: Beijing Second Hospital confirmed that Wang Baoqiang had conducted a paternity test on two children in May 2016, and the DNA similarity was only 2% to 8%. According to the medical results, Wang Baoqiang was not the biological father of the two children.
In this regard, netizens "Zeng Pengyu" posted a Weibo professional rumor, saying that there is no Beijing Second Hospital that can do paternity testing in Beijing, and judicial identification qualifications are required to carry out paternity testing business. There is no such hospital in the list announced by the Beijing Municipal Bureau of Justice; in addition, the expression ratio of paternity testing on kinship is 99.99%, either 99.99% excluded or 99.99% confirmed, and 2-8% of the statements cannot appear.
At the same time, other informed Weibo netizens also posted the "paternity test generator", and the results were consistent with Wang Baoqiang's version, confirming that there was no doubt of spoofing.
Online posting has the characteristics of immediacy and anonymity, but it still reminds netizens not to believe rumors and spread rumors.
Popular science: the principle of personal identification
The theoretical basis for determining the biological relationship is the segregation law of Mendelian inheritance. According to this law, when gamete cells are formed, pairs of alleles are separated from each other and enter their respective gamete cells. Sperm and egg cells are fertilized to form progeny, and the two genomes of the child are one from the mother and one from the father; therefore, the same pair of alleles is one from the mother and one from the father. If the identification results conform to this law, the biological relationship is not ruled out, and if not, the biological relationship is ruled out (except in the case of variation). In most cases, the mother-child relationship is known, and it is required to identify whether the hypothetical father and child are related. At this time, first from the comparison of mother and child genotypes, it is possible to determine the genes in the child's genes that may come from the father (biological father gene, OG). Then observe the genotype of the hypothetical father. If it does not have the biological father gene, the hypothetical parent-child relationship can be ruled out. If it is assumed that the father also has the biological father gene, the result cannot rule out the hypothetical parent-child relationship. Suppose that in one case, the mother is FGA-22/23 and the child is 22/25. From the comparison, it can be determined that the biological father gene is FGA-25. In this case, it is assumed that the father 1 is FGA-22/24; it is assumed that the father 2 is 24/25. It is assumed that the father 1 does not have the biological father gene 25, so it can be ruled out that he has a biological relationship with the child; in contrast, it is assumed that the father 2 has FGA-25, which does not rule out the biological relationship with the child.
