Disclaimer

Attempting to answer the question of paternity without testing the alleged father can be performed with accurate results in a high percentage of cases. This includes testing full or half siblings, a paternal grandparent, or a sibling of the alleged father (aunt/uncle. However, there is a possibility of obtaining inconclusive results. We cannot predict if your results will be inconclusive. An inconclusive result is the product of the statistical comparison and not the DNA test. We use the unique DNA profiles of the suspected relatives to calculate how likely they are to be related versus being unrelated. This statistical comparison is an attempt to approximate reality and is expressed in percent probability. In all cases, it is beneficial to include the mother since she donated half of the child's DNA. This will allow us to focus on the paternal DNA in the child and will decrease the likelihood of getting an inconclusive result.

When we do not have the father to test, we are relying solely on the statistics of a relative that did not contribute DNA at every marker like the father would. When attempting to answer the question of paternity without testing the alleged father by using a close relative, there is a possibility that the outcome might be a misclassification of the relationship. Again, it is beneficial to include the mother since she donated half of the child's DNA to limit the possibility of this happening.

What is a Twin Zygosity Test?

A twin DNA test, also known as a twin zygosity test, compares the DNA profiles of both twins to determine if they match exactly. When the DNA is an exact match, it confirms they are identical twins. However, if the profiles differ, the twins are fraternal.

Many families choose this test simply out of curiosity. In addition, it can be crucial for medical reasons. For example, identical twins are perfect genetic matches for organ or tissue donation, which may be vital in certain health situations later in life.

Unfortunately, even doctors sometimes give incorrect information about twin type. Therefore, the only way to know for certain is by directly comparing the twins’ DNA.

Simple, Non-Invasive Collection

Collecting samples is quick and painless. To begin, use the FDA-approved cheek swabs included in your kit. Next, gently rub the inside of each twin’s cheek to gather skin cells containing DNA. Because this method is non-invasive, it works for any age - from newborns to adults - and ensures accurate, stress-free sample collection.

Surprise results

My twin sister and I have been assumed to be fraternal twins our entire lives as we do not look identical but have more similar mannerisms. . After reading some info that identical twins do not always look exactly alike I was really curious to take the test. Lo and behold this test determined us to be identical 99.99%. Very easy test to do at home and quick results. Thanks to Forever DNA for the confirnation.
