Types of Informational DNA
- Paternity – This test determines the likelihood of father and child. In most cases, the mother’s sample is not needed but can strengthen the results in certain cases.
- Maternity – Determines if a woman is the biological mother of a child.
- Sibling – When it’s not possible to test the alleged father, it may be beneficial to compare the child with a sibling. Unlike a paternity test, two siblings do not always share DNA types in common when considering each marker tested. Each sibling should share half of their DNA in common, but it is not uncommon for two full siblings not to share a number (ALLELE) in common at each genetic location. For a sibling DNA test, the comparison relies on the statistics to determine how likely they are related. Testing the mother will strengthen the results.
- Grandparent – When an alleged father is not able to be tested, at least one of his parents are likely to help. Ideally, both parents of the alleged father, the mother, and the child should be tested for the best results.
- Avuncular – This test will determine if a man/woman is the biological aunt/uncle of a child. This test is ordered when the parents of a child are not available for testing.
- Twin Zygosity – This test determines if twins are fraternal or identical.
- Y-Chromosome – This test requires two males that are believed to be from the same paternal lineage. With each generation, the male will carry an exact copy of the Y-chromosome his father carried.
