If you are twins, are you or your parents wondering if you are identical or fraternal twins. Appearance alone often is not a reliable method for determining twin zygosity because identical twins do not always look exactly the same. Our Twin Zygosity Test can determine whether twins are identical or fraternal, since identical twins have the same genetic profile. Once you order your tests, we will send you a DNA collection kit which contains all the necessary material for the collection and instructions. Please sign the consent form, collect your DNA sample and send sample back to our lab. If any sample's test fails to get valid data, we can provide you 2nd test for free. You only pay the shipping for re-collection kit
