Yes, testing siblings can be used to determine relationship, but it’s not as straightforward as testing the alleged father and child. Siblings share about 50% of their DNA, which means that if the alleged father is the biological father of one sibling, he should share a significant amount of DNA with the other sibling as well.
To determine paternity using sibling testing, a DNA test is performed on both siblings and the alleged father. The test compares the DNA of the siblings to see how much they have in common and then compares their shared DNA to the alleged father’s DNA to see if there is a match.
