DNA NON-LEGAL SIBLING PATERNITY TEST for 2 SIBLINGS

The Process of Sibling DNA Testing

1. **Sample Collection**: The first step in sibling DNA testing is collecting DNA samples from the individuals who are believed to be siblings. This is typically done using a cheek swab, which is a non-invasive and painless method for obtaining DNA. The collected samples are then sent to a laboratory for analysis.
2. **Laboratory Analysis**: In the laboratory, the DNA is extracted from the cells in the samples. Scientists then examine specific regions of the DNA, known as genetic markers, which are known to vary among individuals. By comparing these markers between the individuals, the laboratory can assess the probability of a biological sibling relationship.
3. **Probability Calculation**: The results of the DNA analysis are used to calculate a probability of sibling relationship. This probability is expressed as a percentage, with higher percentages indicating a stronger likelihood of a biological relationship. For example, a probability of 99% or higher is generally considered conclusive evidence of siblinghood.
