Embodiment 1

[0049] Embodiment 1. Verification of the accuracy of the method and system for Y-SNP typing of male individuals of the present invention

[0050] In this example, the male individual is 206 male human anticoagulant blood, whose individual source is known, but in the implementation of Example 1 of this application, its individual source is set to be unknown, and the method and system of this application are used to analyze It performs Y-SNP typing, including:

[0051] 1) Using the DNA acquisition system in the system of the present invention to obtain the DNA of a male individual, 2) Using the composite detection system in the system of the present invention to obtain the genotypes of the 10 Y-SNP sites of the DNA, and according to the genotype Obtain the Y-SNP typing result of the individual, 3) use the deduction system described in the system of the present invention to carry out family investigation, paternity identification, race source inference.

[0052] In this embodim...

Abstract

The invention provides a method and system for Y-SNP typing of male individuals. The method comprises the following steps: acquiring the DNAs of a male individual; acquiring the genotypes of ten Y-SNPsites of the DNAs, wherein the ten Y-SNP sites include M130, M174, M89, M201, M304, M9, M231, M175, M242 and M207; and acquiring the Y-SNP typing results of the male individual according to the ten sites of the male individual. The invention also provides a system for rapid Y-SNP typing of male individuals. The method and system provided by the invention can accurately acquire the genotypes of ten Y-SNP sites of the male individual, so the Y-SNP typing results of the male individual can be acquired; and the Y-SNP typing results can provide data support for family checking, male paternity identification, or ethnic derivation deduction of the individual man.

Description

technical field [0001] The present invention relates to a typing method and system, in particular to a method and system for Y-SNP typing of male individuals. Background technique [0002] China is a multi-ethnic country with 56 ethnic groups identified and confirmed by the government. The distribution of ethnic minorities presents the characteristics of "big mixed population and small cluster". With the rapid development of the economy and the increase of population mobility, the exchanges between various ethnic groups are increasing, and the phenomenon of inter-ethnic cohabitation will become more common. Since the 1990s, terrorism has spread rapidly around the world, and terrorist attacks targeting ethnic and territorial disputes have increased year by year. In recent years, many vicious cases have occurred in our country, seriously endangering social stability and the safety of people's lives and property. The large population flow and the soaring complexity of terror...
