Twin Zygosity DNA Test
Duration:
30 minutes
A twin zygosity DNA test establishes whether twins are identical (monozygotic) or fraternal (dizygotic). Identical twins have identical DNA profiles, while fraternal twins do not. This test compares the DNA of both twins and is over 99.99% accurate. It is performed using cheek swabs and is often done for medical, legal, or personal reasons.
