- DNA is the universal code within your entire body that dictates how everything works. Its structure is a helix composed of a series of pairs of molecules. It is specific and unique to each individual, and cannot change or be altered unless in extreme cases of mutation from radiation. In procreation, the pairs of DNA from father and mother are both contributed equally and create a new DNA sequence of pairs. DNA testing analyzes these pairs for consistencies and inconsistencies.
- Generally both parents will be sampled and compared to the child's DNA. Initially the mother will be sampled and compared to see which of the pairs in the child are from her. With these results, the remaining pairs can allow for the father's results to be excluded or included as the biological contributor. If the mother isn't present, a DNA test can still be done though it is more difficult and further testing may be required.
- DNA paternity testing is 99%+ reliable. An individual's DNA is completely unique - even in identical twins - and, therefore, it is an accurate measure of biological identity. It is performed by accredited labs and is admitted in court as proper evidence. It is a common, reliable procedure that is performed in many situations where paternity is unclear, and can help to aid in answering some serious questions about a person's history and biological identity.
