Which type of DNA test could help spot ancestry from father’s great-grandmother?

How do you find the unknown great grandfather DNA?

To find an unknown parent or grandparent, start by sorting your DNA matches into groups. Many companies help you do this sorting by using a shared or “in common with” feature to show you matches that share DNA with each other. When a whole group has matching DNA, it may mean they all share a common ancestor.

Which genetic marker is the best way to track a maternal ancestor?

Mitochondrial DNA tests trace people’s matrilineal (mother-line) ancestry through their mitochondria, which are passed from mothers to their children.

What is the difference between autosomal DNA and mtDNA?

Our autosomal DNA is inherited from both parents, but Y-chromosomal DNA (Y-DNA) is inherited only from father to son, and mitochondrial DNA (mtDNA) is inherited only from our mother. Shortly after the process of fertilization, the sperms’ mitochondria die away, and the embryo is only left with maternal mitochondria.
