Full siblings are individuals who have the same biological mother and the same biological father while half siblings share only one parent. With this DNA analysis male and female participants are tested to determine whether they share the same biological parent(s) and are therefore full siblings.

When genetic matches between the participants can be found we will calculate the statistical probability of relationship. With the samples of the putative father the DNA test results will show a probability of 99% and more.
