Best for serious genealogists: FamilyTreeDNA Y-DNA and mtDNA tests If you've already taken an autosomal DNA test like the above, FamilyTreeDNA Y-DNA and mtDNA tests provide deeper insight into ...

DNA test kits that trace maternal and paternal lineage, like mtDNA and Y-DNA tests, can potentially go back thousands of years, offering insights into ancient ancestry far beyond recent generations.

Y-chromosome DNA (Y-DNA): Y-DNA tests trace paternal lineage, as the Y chromosome is passed from father to son. It’s a precise method for exploring your paternal line but can only be taken by males.

Each human cell contains 23 pairs of chromosomes that carry DNA within their nucleus. The X and Y chromosomes, commonly referred to as the sex chromosomes, are one such pair. They determine the ...

The genetic information stored in DNA is a living archive of instructions that cells use to accomplish the functions of life. Inside each cell, catalysts seek out the appropriate information from ...
