23andMe® brings the world of genetics to you. 23andMe analyzes variations at specific positions in your genome. These variations, called SNPs (Single Nucleotide Polymorphisms), have the potential to tell you about your traits—such as eye or hair color—and certain health conditions.

Can 23andMe tell me who my father is?

If you are male, your paternal haplogroup tells you about your paternal-line ancestors, from your father to his father and beyond. Because females do not have Y chromosomes, they do not have paternal haplogroups. Females can still learn about their recent paternal ancestry in our Ancestry Composition Report.

23andMe, How It Works!

Will 23andMe tell me if I have siblings?

Your Connections. First, share your profile with your sibling(s) from the Your Connections page.

Are 3rd cousins considered family?

Third cousins are always considered to be relatives from a genealogical perspective, and there is about a 90% chance that third cousins will share DNA.

Why you shouldn't do a DNA test?
