This DNA test definitively determines whether twins are identical or fraternal.

When twins are born, pathological examination of the placenta can be performed to determine zygosity. However, studies have shown that this method is not 100% accurate. Scientists recommend DNA testing to accurately determine zygosity.

Identical twins come from one fertilized egg, called a zygote. The zygote, which usually develops into one child, grows and splits early in development to form two embryos – Identical twins. Because the twins come from one egg and one sperm, they have exactly the same DNA.

Fraternal twins, on the other hand, develop when there are two different eggs in the mother’s womb that are fertilized by two different sperms. Fraternal twins will not have exactly the same DNA.

Once we receive your samples, your AABB-accredited court-admissible test results will be completed in as little 5 business days. Rush testing options are available.
