Twin Zygosity Test
Twin zygosity refers to whether twins are identical or fraternal.
Identical (monozygotic) twins develop from a single fertilized egg that splits into two, resulting in two embryos with identical DNA. They always share the same sex.
Fraternal (dizygotic) twins develop from two separate eggs fertilized by two different sperm. They share about 50% of their DNA, similar to non-twin siblings. Fraternal twins can be the same sex or different sexes.

The process involves collecting DNA samples from each twin, typically through painless cheek swabs. These samples are then analyzed in a laboratory to compare their unique genetic profiles. Identical twins, who originate from a single fertilized egg, will have nearly identical DNA profiles, while fraternal twins, who develop from two separate eggs, will exhibit significant genetic differences. The results of the DNA analysis provide accurate information about the twins’ zygosity, which can be valuable for various reasons, including medical research and personal curiosity.
