DNA Relationship Probability Calculator
In the event an alleged father is not available for testing, his relatives can take a DNA Test to reconstruct his genetic profile and determine if there is any relationship between him and the child.

The average probability is derived from multiple simulations performed across Caucasian, Hispanic, African American, Native American, and Asian population databases assuming analysis with the marker identifier profile and does not guarantee any specific testing outcome. The actual results of testing are dependent on the genetics of the individuals tested.
