* A value of “0” for any marker indicates that the lab reported a null value for this marker. Our labs retest all cases of null values multiple times to confirm their accuracy. Mutations causing null values are infrequent, but fathers pass on null values to their sons just like other Y-DNA mutations. Therefore, related male lineages such as a father and a son are likely to share null values.
