Paternity test blood type matching chart and interpretation
A blood group matching chart is an essential tool when conducting a paternity test. Below we will explain the blood type matching table in detail to understand the results of the paternity test under different blood type combinations.
The significance of the blood type matching table
The blood type matching table can show the different blood type combinations between the father, mother and child, and can deduce the biological relationship between parent and child based on the genotypes of different blood types. Specifically, there are four types of ABO blood types: A, B, AB, and O. There are two types of Rh blood types: Rh positive and Rh negative. Different blood type combinations of parents and children will produce different identification results.
Steps of paternity test
First, DNA samples need to be extracted from relatives, including parents and children, and then PCR amplification is performed to copy the DNA in the sample to a sufficient amount, and then fluorescent DNA sequencing is performed to obtain information about the sample DNA. Finally, based on the comparison of the DNA information of the parents and the child, it can be determined whether there is a parent-child relationship.
Judgement of paternity test results
If parents and children have the same genotype, it can be determined as a parent-child relationship. For example, if a parent with blood type A only has the genotype of type O blood, then the child must be AO or AA type. If the child is B or AB type, it cannot be They are the biological children of this couple.
If the genotypes of parents and children are mutually exclusive or inconsistent with the rules, it can be determined that there is no parent-child relationship. For example, there is no biological relationship between a mother with a negative blood type and a child with a positive blood type.
Applications of paternity testing
Paternity testing can be helpful when people need to clarify the relationship between their children and deepen understanding and trust between family members. In addition, in terms of law, paternity testing is also widely used, such as providing evidence in divorce proceedings, inheritance rights, property distribution, etc. Its role cannot be ignored.
Summary
In the process of paternity testing, the blood type matching table is a very important tool. The accuracy of the testing results also mainly depends on factors such as sample preparation and testing technology. Although the implementation of paternity testing may affect family relationships and people\’s emotions, in some cases it is necessary to solve some long-standing problems and make people\’s lives clearer and more harmonious.
