When two people have biological relation, they share part of their genomes, so parts of their genomes are the same. For example, parent and his/her biological child have 1/2 of their genes in common; grandparent and grandchild have 1/4 in common; aunt/uncle and niece/nephew have 1/4 in common; cousins have 1/8 in common; half siblings have 1/4 in common.


When we test whether two people have biological relationship, we will first carry out their DNA analysis and compare two mutually exclusive hypotheses:
A) the two people have biological relation; B) the two people don’t have biological relation. If the probability of hypothesis A is far greater than the hypothesis B, and then we consider they have the biological relation; If not, we concede we don’t have enough evidence.


Because two relatives are usually less related than parents and their children, the result of relationship testing is not as defined as a parentage testing. Therefore, we usually don’t perform relationship analysis on distant relatives, such as those less related than biological cousins.
