DNA testing for Twin Zygosity

"Are they identical or fraternal?" This is probably the most common question asked of parents of multiples. Many people do not understand what they are really asking, assuming that it is just a matter of twins having similar physical appearance.

Identical

twins form when a single fertilized egg splits into two genetically identical parts. The twins share the same DNA set, thus they may share many similar attributes. However, since physical appearance is influenced by environmental factors and not just genetics, identical twins can actually look very different. Identical twins are always same-sex sets.

Fraternal

twins develop when two separate eggs are fertilized and implant in the uterus. The genetic connection is no more or less the same as siblings born at separate times. They may look alike, or they may not.
