DNA TESTING BROTHERS - Y CHROMOSOME DNA

(Click Here to Order a Free Collection and Information Kit for Sister to Sister testing)

There are two different testing options for DNA testing brothers.

1. Y Chromosome testing. NZ$595 for 2 persons ($175 for each extra person)

Y chromosome testing is used to see if two or more male persons have the same biological father. If you also (or only) wish to know if they have the same Mother, then you additionally require a mitochondrial DNA test, or a Full Sibling DNA test.

Y chromosome testing is your least expensive option while obtaining very high accuracy (99.9 %+). All men have one Y chromosome and pass that same Y chromosome to all their sons. Therefore, we can test accuracy the Y chromosome and deduce if they have the same male ancestor (i.e.. can also use Y chromosome test for grandfather-grandson, uncle-nephew, etc.)

If you want to test if two brothers have the same mother, then a Y chromosome test is not sufficient, and you will require a full sibling to sibling DNA test.

2. Mitochondrial DNA test. NZ$595 for 2 persons ($175 for each extra person)

Mitochondrial DNA testing is used to see if two or more male persons have the same biological mother.

Mitochondrial DNA is passed down from Mother to children. So, brothers to the same mother will have the exact same mitochondrial DNA.
