Genetic relationship identification method, system and equipment

Abstract

The invention discloses a genetic relationship identification method, system and device. The method comprises the following steps: utilizing a genetic relationship genealogy; constructing a gene treeby taking individual paternal line genes and maternal line genes of non-builders with obtained gene data as root nodes and taking individual paternal line genes and maternal line genes of root node genes as leaf nodes; for the leaf node, if gene data cannot be obtained, taking a gene source individual paternal line gene and maternal line gene as new leaf nodes until the leaf nodes belong to the builder individuals or the gene data individuals can be obtained; and carrying out inheritance vector probability symmetry or consistency judgment on subsets obtained by carrying out gene set segmentation by utilizing the gene tree. During pedigree probability calculation, the memory space occupied by the inheritance vector set is compressed, the calculation amount is reduced, and forensic genetic relationship identification, parent seeking and the like in a larger genetic pedigree range are achieved by using limited memory resources. The ability of an existing information management system or website to process the problems of genetic relationship analysis, identification, retrieval, matching and the like is improved.

Description

technical field [0001] The present application relates to the field of kinship identification, in particular to a method, system and equipment for kinship identification. Background technique [0002] With the development of our country's economy and the improvement of people's legal awareness, there are more and more disputes over paternity testing. Paternity testing includes paternity testing. The typical paternity testing triplet refers to the determination of the mother-child relationship. It is necessary to identify whether the suspected father is the child's own. Father, in addition, also includes the identification of doublets where only one parent and child are involved, and the identification of both parents is suspected of triplets where the relationship between parents and children is uncertain. Relying on DNA technology for paternity testing has been widely recognized. The identification process is mainly based on the results of DNA typing, using genetic laws to ...

Problems solved by technology

[0004] When the number of genetic markers is large and linkage problems need to be considered, small and medium-sized computers or servers are limited by hardware resources, and the range of pedigrees that can be solved is limited. When the pedigree is large enough, large-scale computers will also be limited by hardware resources when performing linkage analysis.
