Twin Zygosity
Confirms whether twins are identical (monozygotic) or fraternal (dizygotic).

Are twins identical (monozygotic) or fraternal (dizygotic)? Our twin zygosity testing uses DNA comparison to provide a clear answer. While identical twins share nearly identical DNA, fraternal twins share about 50%, and our test offers definitive proof. This can be useful for medical records, academic research, or family curiosity. We offer this testing on-site across Palm Beach County with professional, confidential sample collection and rapid results you can trust.
