Successful reconstruction of the human gene has died for 200 years

An international research group funded by the Biological and Pharmaceutical Company deCODE Genetics (Iceland) succeeded in replicating part of a man who died in 1827.

It is worth noting here that the group did not have the original tissue sample. The DNA reconstruction task is entirely based on the study of DNA samples from the descendants of the dead.

Specifically, scientists collected the genetic information of many Icelandic people to reconstruct the DNA structure of a black slave - migrating here in the early 19th century. At that time, he was a man. The only African root with unique genetic resources.

This man named Hans Jonatan married and had children with a white native woman. His children and grandchildren later brought a portion of Jonatan's DNA. In addition, Iceland is also in the group of countries that possess the world's leading coverage of genetic data - data for more than a third of citizens.

Taking advantage of this, the team searched for the descendants of Jonatan, originally from 788 and retreating to 182 people. After a period of work, they reported being able to use the data collected to partially reproduce Jonatan's DNA structure without using tissue samples from him.

In addition, scientists also tracked down the origin of Jonatan: his mother was an African slave at a plantation in St. Petersburg. Croix - a Danish colony at the time, his father was a white European.

Although the research's success is largely based on particularly favorable conditions, the research team still believes in the potential application of the method, such as in the genealogy completion.
