Genebase Sibling DNA Test

From $150 TAKE THE TEST

The Sibling DNA test report will provide you with a full sibling index and a half sibling index. The full and half sibling indexes will tell you whether the siblings are most likely to be full siblings (two parents in common), or half siblings (only one parent in common) or not related at all (no parents in common).

Every person has two copies of each gene. One copy comes from the mother and the other copy comes from the father. Thus, one half of the genetic material in our body is inherited directly from each of our two parents. When a DNA sibling test is performed, the DNA laboratory examines the DNA of each sibling and then compares them to generate a full sibling index and a half sibling index. Individuals who are full siblings are expected to have a full sibling index that is greater than 1.0 and the value of the full sibling index will be higher than the value of the half sibling index. Individuals who are half siblings are expected to have a half sibling index that is greater than 1.0 and the half sibling index will be greater than the full sibling index. Individuals who are not related are expected to have a full sibling index that is less than 1.0 and a half sibling index that is less than 1.0.
