Kinship Calculator

Important! This calculator is based on a prior probability of 0.5 and is intended for two individuals to determine the likelihood that they are close biological relatives. It is not intended for random screening of large numbers of unrelated individuals to search for chance matches as the prior probability value would no longer be 0.5 and the formula used in this calculator will no longer hold true.
