Embodiment 1

[0054] Please refer to figure 1 , the embodiment of the present invention provides a kind of kinship identification method, the kinship identification method is a kinship identification method without the participation of reference parents, comprising the following steps,

[0055] Step S101, obtaining the first allele and the second allele of the person to be identified, and determining the first gene frequency of the first allele and the second gene frequency of the second allele.

[0056] Optionally, the specific implementation of step S101 is:

[0057] Using a preset kit to test the genotype of the preset site of the person to be identified to obtain the first genotype;

[0058] A first gene frequency of the first allele and a second gene frequency of the second allele are determined based on the first genotype.

[0059] In the embodiment of the present invention, the genotype of the predetermined locus of the person to be identified is tested using a preset kit to obtain...

Embodiment 2

[0079] Please refer to figure 2 , Embodiment 2 of the present invention provides a kind of kinship identification method, and this kinship identification method is the kinship identification method that has reference parent to participate in, and this method comprises the following steps:

[0080] Step S201, obtaining the first allele and the second allele of the person to be identified, and determining the first gene frequency of the first allele and the second gene frequency of the second allele.

[0081] Step S202, acquiring a first occurrence number of the first allele in the genotype of the accused ancestor and a second occurrence number of the second allele in the genotype of the accused ancestor.

[0082] Step S203, acquiring the level of kinship between the person to be identified and the accused ancestor.

[0083] Step S204, obtaining the third occurrence number of the first allele in the genotype of the reference parent and the fourth occurrence number of the second ...

Embodiment 3

[0153] Embodiment 3 of the present invention provides a kind of kinship identification device, please refer to Figure 4 , in one implementation manner, the device for identifying kinship includes: a first acquiring unit 301 , a second acquiring unit 302 , a third acquiring unit 303 , and a determining unit 304 . in,

[0154] The first acquisition unit 301 is configured to acquire the first allele and the second allele of the person to be identified, and determine the first gene frequency of the first allele and the second gene of the second allele frequency;

[0155] The second acquisition unit 302 is configured to acquire the first occurrence number of the first allele in the genotype of the accused ancestor and the second occurrence number of the second allele in the genotype of the accused ancestor The number of occurrences;

[0156] The third acquisition unit 303 is configured to acquire the level of kinship between the person to be identified and the accused ancestor;...

Abstract

The invention is suitable for the technical field of forensic material evidence science, and provides a genetic relationship identification method and a terminal device. The method comprises the stepsof obtaining a first allele and a second allele of a to-be-identified person, and determining a first gene frequency of the first allele and a second gene frequency of the second allele; obtaining afirst occurrence frequency of the first allele in a controlled ancestor and a second occurrence frequency of the second allele in the controlled ancestor; obtaining a genetic relationship level of theto-be-identified person and the controlled ancestor; and according to the genetic relationship level, the first gene frequency, the second gene frequency, the first occurrence frequency and the second occurrence frequency, determining a first genetic relationship between the to-be-identified person and the controlled ancestor. Therefore, the identification process can be simplified.

Description

technical field [0001] The invention belongs to the technical field of forensic physical evidence, and in particular relates to a kinship identification method and terminal equipment. Background technique [0002] Kinship testing refers to the identification of whether there is a specific kinship relationship between two individuals through the detection and typing of various genetic markers according to genetic laws, which is one of the main tasks of forensic physical evidence. [0003] According to the purpose of identification, the identification of kinship can be divided into two types: identification of direct kinship and identification of collateral kinship. The former includes identification of relationships between father and son, grandparents, and grandparents, while paternity identification is the most common in this type of work. Especially paternity identification; the latter such as uncles and nephews, compatriots / half-siblings, cousins, etc. At present, the id...
