A mitochondrial DNA test (mtDNA test) determines the probability of the existence of a relationship on the maternal side. Mitochondrial DNA has the distinction of being completely transmitted from mother to both sons and daughters. As the transmission is complete, all the children of this mother and her grandchildren will have the same mitochondrial DNA.
A Twins DNA test allows to check whether two twins were born from the same egg (mono-zygotic) or if they are born of two separate eggs (zygotic). A twin DNA test is also known zygosity test. Why a twins DNA test? In most cases, the parents or the twins are taking this test out of
A maternity DNA test verifies that the alleged mother is the biological mother of the child, without having to test the father. We inherit our genetic profile from our two parents, half from our mother and half from our father. A maternity DNA test compares the DNA profile of a child with he DNA profile
An aunt or uncle DNA test is also called avuncular test and can conclude paternity, even when the alleged parent is not available for DNA sampling.

This test can be preformed even when there’s no DNA sample from the alleged father. The Y-Chromosome test confirms paternity through
Doubts about a brother or sister? Do you share the same parents? A Sibling DNA test can confirm a biological relationship between brothers and sisters.
