The Twin Zygosity DNA Test is ideal for a mother who wants to validate the determination of fraternal vs. identical twins.

The importance of determining whether a set of twins are fraternal or identical goes beyond their physical appearance. It can also be a factor in paternity. A set of identical twins will share the same father. Unlike identical twins, fraternal twins can have two different fathers. Usually, when twins are born, the physician is able to tell whether twins are identical or fraternal by examining the placenta. However, if there is doubt about the determination that was made at the time of birth, a Twin Zygosity DNA test will reveal the truth.

This test compares the twins’ DNA profiles to see whether they are a match. If they are an exact match it proves they are identical twins.
