Description

This DNA test definitively determines whether twins are identical or fraternal by testing the two individuals in question.

Identical twins come from one fertilized egg, called a zygote. The zygote, which usually develops into one child, grows and splits early in development to form two embryos, creating twins with the exact same DNA. Fraternal twins, on the other hand, develop when two different eggs in the mother’s womb are fertilized by two different sperms. Fraternal twins will not have exactly the same DNA.

Court admissible DNA testing requires strict sample collection procedures and stringent documentation requirements. Endeavor DNA Laboratories maintains a network of approved sample collection sites across the United States. Our expert case managers will work with you to schedule a sample collection in your area at a time convenient for you.

All Endeavor DNA Laboratories’ twin zygosity tests utilize stringent, validated testing procedures and include up to 22 STR loci plus the gender identification marker amelogenin in order to achieve 100% accurate results.
