Description
Twins are usually categorized as identical or fraternal at birth by a doctor based on physical features and placental examination, although these determinations aren’t always accurate. A twin DNA test, often called a zygosity test for twins, can determine once and for all if your twins are identical or fraternal. Peace of Mind’s Twin Zygosity Test compares the genetic markers for each twin to see if their profiles are identical/ match in anyway and provides reliable results regardless of the twins’ age.
