Your first friend wins — mostly. Identical twins have almost identical DNA. We used to think identical twins had identical DNA, because they come from the same fertilized egg, which had only one complete set of DNA in the first place. That fertilized egg and its single set of DNA split to form twin embryos — each with its own set of DNA, identical to the other. But we admitted one small quibble: the DNA sets will be identical, unless one fertilized egg's DNA mutates. Such mutations, however, are normally so tiny that DNA analysis can't detect them.
Our staff works hard to make the DNA Identity Testing Center your choice of provider for all DNA testing services. We ensure superior quality, service and convenience to our clients. In our commitment to providing convenience, please know that we provide a free DNASwabTM Home DNA Collection Kit for use in all types of private DNA tests.

Identical Twins
The last decade of forensic science has been dominated by genetic analysis. Lawyers now focus on DNA testing to prove the guilt or innocence of those accused of crimes, pushing traditional techniques such as fingerprint analysis into the background. Ironically, however, fingerprint analysis could be used to solve a key conundrum of genetic analysis — how do we tell about identical twins? Identical twins develop when a single fertilized egg splits in two, leading to two embryos. Because they both came from the combination of the same egg and sperm, they have identical DNA, barring the generally undetectable micro mutations that begin as soon as cells start dividing. |

DNA Testing and Twins
DNA testing can be used to confirm if two individuals are identical or non-identical twins. This test may also be required to confirm suitability for organ or bone marrow donation. 'Identical' or 'monozygotic' twins develop from a single fertilised egg which then divides and develops as two separate embryos. Their DNA is therefore exactly the same, they will be the same sex and they are more likely to look like each other. |
