Identical or Fraternal Twins?
Have you ever wondered if your twins are identical or fraternal? Or are you a twin who is curious about whether your counterpart is your identical counterpart? If so, Beta Paternity has a DNA test that can help.
Beta Paternity’s twin zygosity test examines the genetic profiles of twin siblings to determine whether they are identical or fraternal. Identical twins will have the same DNA profile, while fraternal twins will not. By comparing the siblings’ DNA markers, our expert analysts can tell with certainty what type of twins they are.
Identical twins have matching DNA profiles because they developed from a single zygote (one egg and one sperm cell) that split in two during its early development. Fraternal twins, in contrast, developed from two different zygotes—two eggs that were fertilized by two sperm cells. For this reason, the genetic profiles of fraternal twins can be as dissimilar as any non-twin siblings’ profiles can be.
