Unlike the Y-chromosome or mitochondrial DNA test, AncestryDNA® uses an autosomal DNA test that surveys a person’s entire genome at over 700,000 locations. It covers both the maternal and paternal sides of the family tree, so it covers all lineages.
Can AncestryDNA tell me who my father is?
Ancestry DNA results can help indirectly reveal your paternal line. If your father has not done a DNA test with Ancestry DNA, then the website will not be able to tell you directly who your father is. Even so, you may be able to determine who your biological father is based on your closest DNA matches.
How can DNA profiles trace your paternal ancestry?
A man’s paternal lineage can be traced using the DNA on his Y chromosome (Y-DNA), which, like many European surnames, passes from father to son. DNA profiling provides a genetic path that follows the surname through the years.
What DNA Does a woman inherit from her father?
While women do inherit 50% of their DNA from each parent, men inherit about 51% from their mother and only 49% from their father.

Is AncestryDNA accurate?
Accuracy of the Reading of the DNA
Accuracy is very high when it comes to reading each of the hundreds of thousands of positions (or markers) in your DNA. With current technology, AncestryDNA has, on average, an accuracy rate of over 99 percent for each marker tested.
Why is AncestryDNA not accurate?
What else might make your ancestry results inaccurate? … The results are further skewed by the fact that certain ancestry information markers used by any particular test may come from only your paternal line (Y chromosome) or your maternal line (mitochondrial DNA). Tests using these markers are less accurate.
Why did my AncestryDNA results disappear?
Because what AncestryDNA knows about the relationships between regions and DNA has improved, some regions may disappear from your estimate. This may be particularly true of regions with a low percentage on your earlier estimate.
