DDC Laboratories India Sibling-ship DNA Test - Kinship Test DNA testing of Sibling-ship is designed to determine genetically whether the siblings (brother and sister) are biologically related to each other or not and verify if they are full siblings, half-siblings or not siblings at all.
There are two types of DNA Sibling-ship Tests for DNA samples: 
Half-Sibling-ship DNA tests: In this case, there are two individuals who share 25% of their genes from only one biological parent in common.

Full-Sibling-ship DNA tests: In this case, two individuals share the same (50%) biological parents.
Siblings DNA Test between brothers If the siblings are male and want to know if they share the same biological father, we suggest a different type of sibling DNA test called the Y chromosome test. This test is extremely accurate. If women wish to establish whether they have a common paternal lineage, they can ask a close relative to have a Y chromosome test on their behalf.
Siblings DNA test between sisters If the test participants are women and their goal is to know if they have the same biological father, EasyDNA suggests an X chromosome test. It is important to keep in mind that with the X chromosome test, the mother's sample will be needed in cases where the women tested have the same mother.
