A Guide to complex DNA Testing
- Grandparent DNA Testing. To establish the biological grandparents of a child. Also, this test can show paternity in an indirect way.
- Also. we can use a number of other combinations to test the above.
The Complex DNA Test Explained
We produce a DNA test profile for each test participant. The test analyses different genetic locations on the DNA strand. We identify each allele (alternating form of DNA) at each location using a number. Then, we compare the DNA profiles of each test participant. In this case, the premise is that related individuals should have more DNA in common than unrelated individuals.
Inconclusive Results and Test Limitations
- The number of allelic matches within the DNA profiles.
- The likelihood of finding the same allele at the same DNA location. We compare this against a random, unrelated individual with the same ethnicity.
How are Complex DNA Test results interpreted?
- The alleles shared between potential relatives are common within the relevant general population. In other words, there is insufficient genetic evidence to confirm which relationship exists.
- There is a low level of allelic (number) matches in the DNA profile. This is due to the chance nature of inheriting alleles within families (as explained above).
- Mutation causing mismatches at further locations within the DNA profile.
