DNA Sibling Test – Types

In the DNA sibling test, two children are tested to determine whether they share the same biological parent or parents. Two individuals born of the same biological parents share much more of their DNA than individuals that are not related to one another. There are two types of DNA Sibling Test:

• Half Sibling Test: This test is performed when two alleged siblings believe they only share one biological parent (as in when two siblings know that they do not have the same mother and are trying to determine if they have the same father). In other words, a half-sibling DNA index can be obtained to determine whether the siblings share only one common parent, versus two common parents.
• Full Sibling Test: This test is performed when two siblings share one biological parent and would like to know if they share the other parent as well (as in when two siblings know they have the same mother and wish to find out if they have the same father).

Ormond Quay Paternity Services (OQPS), a leading DNA test provider in Ireland offers DNA sibling test to help two individuals verify whether they are full or half siblings. On an average, full siblings (share both biological parents) have 50% of their DNA in common, half siblings (share only one biological parent) have 25% of their DNA in common. With the results of a DNA sibling test, OQPS can determine if two people are siblings based on the amount and specific type of DNA they have in common.
