Grandparent DNA Test Details


Short Description

Biological parents equally contribute 50% to their child’s DNA, so that one-half of his DNA comes from each parent. When that child becomes a parent, they, in turn, contribute half of their DNA to their child. Therefore, 25% of the grandchild’s DNA comes from each grandparent, through their biological child.

Detail Description

DNA Labs India does 46 Marker Grandparents DNA Test to get the highest accurate DNA Test results.

Half of our DNA markers belong to the mother while the other half belongs to the father. One-fourth (1/4) of our genetic markers belong to our grandparents.

The Grandparent Lineage Test is performed to determine whether a couple (either of the grandfather or the grandmother) is a biological grandparent of the child. Grandparentage Tests are done when an alleged father is not available to take the test. Through this test, the lineage is established without any need for an alleged or biological father at all.

Although the Grandparentage Test can be performed with or without the child’s mother, the mother’s participation is highly advised because it aids in excluding half of the child’s DNA when compared to her DNA. The remaining half of the child’s DNA markers are to be matched with that of grandparents’ DNA markers. If both the grandparents are present, the result of the test is more accurate than only either of the grandparents being present.

Reasons for a grandparent DNA test

The grandparent DNA test is often required when parents of the alleged father or indeed the biological mother are not available. This is to test a child’s missing links in their biological relationship with the family.

In this case, if the alleged father is unavailable for a paternity test, the next step is to do a grandparent DNA test of the alleged father’s parents to answer the child’s relationship with the alleged father.

Other cases include the grandparents questioning if the child is their biological grandchild. DNA tests such as these can provide the answers to bring families closer together.

How does Grandparent Testing Work?

Biological parents equally contribute 50% to their child’s DNA, so that one-half of the child’s DNA comes from each parent. When that child becomes a parent, they, in turn, contribute half of their DNA to their child. Therefore, 25% of the grandchild’s DNA comes from each grandparent, through their biological child.

The test works on the fact that a child inherits half of his or her DNA profile from each of their parents. In other words, half the child’s DNA profile matches their mother and the other half matches the father.

DNA samples are taken from mouth swabs to generate a DNA profile for each test participant. Next, the DNA profiles and determine the likelihood of a relationship. In this case, the likelihood that the participants are biologically related as grandparent and grandchild.

Can I use Grandparents to establish paternity?

Yes, grandparents can be tested to establish paternity. For some families, proving paternity with a DNA test can be a challenge, particularly if the alleged father is not available for testing or is unwilling to provide a DNA sample.

If the alleged father is unavailable, it is possible to undertake a grandparentage test if you use a lab that has expertise with this type of testing.  A grandparentage test reveals if the child being tested is related to the paternal grandparents, and in doing so can prove the identity of the child’s father.
