family doctor online: what is the DNA paternity test?
Xiao Yanqing, director: paternity testing is based on the detection of human genetic markers, according to genetic law analysis, the controversial relationship between parents and children identification. A person's genetic material (i.e., the DNA sequence) is unique except for identical twins, half of them from father and half from mother. Under normal circumstances, an individual's genetic material will remain unchanged in the lifetime, and in between is the same (such as skin and blood), so it can be detected by DNA sequence to determine the parent-child relationship.
