3, augmentation detection
Carry out pcr amplification, genetic analyzer detection and the final somatotype result that obtains according to embodiment 1.
The ultimate principle of paternity test is: according to mendel's law, parental generation genotype determiner is for genotype.Under the prerequisite that does not have transgenation, somatotype mistake: 1. child's pair of alleles must be one from father, one from mother; 2. the allelotrope that can all have with parents of child.
Detect a routine father-woman-female triplet parentchild relationship with embodiment 1 method, it the results are shown in accompanying drawing 11.
In accompanying drawing 11, each row is followed successively by child, father, mother's corresponding detected result in each chromatic graph.
Obtain the paternity test father of this experiment-son-female gene type such as following table 1 by accompanying drawing 11:
Table 1:
PI is paternity index, claim again the parentchild relationship index, refer to suppose the ratio that the father provides the possibility (X) of obliged gene and man at random that the possibility (Y) of obliged gene is provided, expression hypothesis father be child own father's possibility greatly what times, i.e. PI=X/Y than man at random for the child own father.
PI=X/Y＝∑f×c/∑f×p
F represents that breeder mother is to the essential allelotrope chance of child;
C represents that controlled father is to the essential allelotrope chance of child;
P represents that the man equals essential gene frequency to the essential allelotrope chance of child at random;
Associating paternity index CPI is each product of linked gene seat PI not;
Relative parental right probability (RCP)=(CPI/(CPI+1)) * 100%;
According to above-mentioned calculating, father-son in this experiment-female triplet paternity test RCP value is 0.99999999936 %, assert parentchild relationship.
Detection system of the present invention is applicable to the amplification through leaching process gained dna sample simultaneously, such as the amplification of the samples such as blood/trace, buccal swab, tissue, seminal stain, salivary stain, hair, bone source dna sample.
The embodiment of the invention can be utilized and extract the human gene group DNA obtain and be parent material, and nucleic acid amplification that only need about 40-50min can carry out the STR somatotype and detect, and has greatly shortened the final somatotype result's of acquisition sample time.
Above-described embodiment, the present invention embodiment a kind of more preferably just, the common variation that those skilled in the art carries out in the technical solution of the present invention scope and replacing all should be included in protection scope of the present invention.
