Can China test DMA in 1980s?

You mean DNA identification, right If so, the answer is as follows:

DNA identification, that is, paternity test, was first used only in the judicial field, and the judicial department used DNA paternity to identify some cases. Common cases include custody, inheritance, disputes and the identification of rapists. A woman was raped and gave birth to a child. There is a parent-child relationship between children and rapists, and the facts can be confirmed by DNA identification. The above situation is more common, and judicial expertise is also one of the earliest reasons for paternity testing.

The first paternity test in the world was 1985, a little boy in Ghana. The little boy applied to the Immigration Bureau to immigrate to England and said that his mother was English. At that time, the British Immigration Bureau applied for judicial expertise to identify the parent-child relationship between the boy and his mother. The final identification result was positive, which allowed the little boy to immigrate to Britain from Ghana.

The earliest paternity test in China was 199 1 year. At that time, the public security department encountered a divorce custody dispute case. The Ministry of Public Security made an exception and applied DNA paternity technology, which was limited to criminal investigation technical appraisal at that time, to civil cases. Finally, the father and the 5-year-old son drew blood at the same time, and the identification results showed that there was no blood relationship. On this basis, the court finally ruled that the father no longer bears the obligation of raising children, and the mother bears the appraisal fee, legal fees and the maintenance paid by the father in recent years. This is DNA paternity's initiative in China, and this little-known technology gradually unveiled its mystery.

Later, with the progress of society and the development of the times, the scope of paternity test gradually expanded, no longer limited to judicial identification, and personal paternity test began to appear.
