Are my twins identical? Is there a DNA test that can prove it? Read our latest expert guide to find out…
Are my twins identical?
Twins will be identical or fraternal depending on how the babies were formed. The only way to know for sure whether twins are identical or fraternal is through DNA twin testing (also known as zygosity testing).
The twin test involves analyzing tiny amounts of DNA from inside each twin’s mouth. A simple mouth swab is all that is needed to collect these samples. This is a very simple and painless procedure. When these samples are returned to our laboratory for testing, our DNA scientists examine specific markers present in repeat sections of DNA and compare these between the tested individuals. Identical twins will share the same DNA profile whereas non-identical siblings will have different DNA profiles.Order a Twin Zygosity DNA Test Online
Fraternal (or non-identical twins) are the result of separate fertilized eggs and are known as dizygotic, which means they have two zygotes. These babies share DNA in common as in the case of siblings from different births. However, they are no more alike than any other brothers or sisters, and they may be both male, both female, or one of each.
Identical twins are formed from a single fertilized egg, which went on to split into separate embryos. This means that these babies’ DNA is exactly the same and they are known as monozygotic.Identical vs fraternal twins
However, it’s not always clear in utero whether twins are identical. They don’t always share the same placenta and sac: it all depends on when the eggs splits. The only way to know for sure is through DNA twin testing.
