Concerned about how exactly are sensational Paternity DNA tests are? Paternity DNA test results are accurate enough to confirm or exclude paternity. In this blog, you will learn about how DNA results are arrived at.
Everyone has two copies of alleles for every gene they have in their nucleus. You get one copy from your father and one from your mother. The two alleles from everyone’s samples are evaluated and compared at specific locations on a chromosome between all the tested individuals.
If there is a match of alleles between tested individuals, then there must a biological relationship between them. If there are two or more mismatches between the alleles of tested individuals, then there is no biological relationship between them. Learn about DNA tests for legal reasons HERE
What does DNA testing involve?
DNA testing involves a forensic scientist conducting diagnostic testing and reading the DNA sequence in each sample. The scientist then calculates the probability of the tested individuals being related.
A calculation of 99.99% leads to the conclusion that the alleged parent contributed to the assessed sample and therefore is declared as the child’s biological father.
A calculation of 0% shows that there is no match between the child and the alleged parent, and the man is therefore excluded as the child’s biological father.
If a relative of the alleged parent could be the biological parent of the child, the laboratory must have this information. This is taken into consideration during the statistical calculation.
It is recommended that people collect the samples first thing in the morning before brushing, them to avoid contamination with food or drink.
To ensure the accuracy of the results, all samples are assessed twice. LEARN MORE
