Twin DNA Test
Have you ever wondered if your twins were identical or fraternal? Physical appearance sometimes is not a reliable method to determining twin type. Identical twins don’t always look identical and fraternal twins can sometimes look very much the same. This can be very confusing. In some cases twins grow up never knowing for sure if they are truly identical or not.
DID YOU KNOW:
Identical twins often share a single sac with placenta and amniotic membranes. Fraternal twins normally form into two separate sacs. However, up to 25% of the time this method is not accurate. At the time of birth the physician normally determines the twin type by examining whether both fetus’s share the same sac. The determination is visual and not always accurate and can be very misleading. Studies show twins can have two outer sacs and still be identical, and in other cases the placentas of fraternal twins can sometimes fuse together and appear as one.
The only for sure way to conclusively determine whether twins of the same sex are identical is through Twin DNA testing.
Fraternal twins are similar to full siblings that are born at different times, they usually share similar traits such as eye color, hair texture, hair color, height and weight.
Identical twins share the exact same profile, traits and sex. Physical attributes of identical twins are normally the same but can be quite different.
