Understanding your results

"Every Genetrack test report is fully comprehensive and easy to understand. A summary of the conclusions of the test are provided along with the full DNA profile for each individual tested."

Understanding your sibling test report

Your sibling test report will provide you with an indication of whether two individuals are biological siblings. Your sibling test report will provide values which indicate whether two individuals are siblings or unrelated, and will also provides values which indicate whether two individuals are full or half siblings.

Determination of whether two individuals are related. Your sibling test report will provide you with a ¡§sibling index¡¨. A sibling index value over ¡§1¡¨ is consistent with the two individuals being biologically related. A sibling index value under ¡§1¡¨ is consistent with the two individuals being unrelated.

Determination of whether two individuals are full siblings or half siblings. Your sibling report will also provide you with a ¡§full sibling¡¨ index value and a ¡§half sibling¡¨ index value. A full sibling index value which is greater than the half sibling index value is consistent with the individuals being related as full siblings. If the half sibling index value is greater than the full sibling index value, then the results are consistent with the sibling being half sibling (sharing only one parent in common).

Your sibling test report will provide all results and index values along with the full genetic profile of each individual tested.
