Sounds like every retailer in the universe is getting Black Friday Fever! Here's a link to
FamilyTreeDNA to read about what they're offering "today only"!
"Family Finder" is their terminology for an
autosomal DNA test. See? "Family Finder" is easier to say! But the difference between Y-
DNA and
mtDNA tests is this: Of the 23 pairs of
chromosomes in the nucleus of the human gene, one pair is the
sex chromosome the "X-X" or the "X-Y" . Y-DNA is carried only by and passed along by males. the mtDNA is actually outside the nucleus and is passed down only by the female but both males and females have the identical mtDNA. So what about the fact that both Mon and Dad pass down various traits? That's where autosomal DNA plays a part. That is where the half contributed by Mom and combines with the half contributed by Dad. This allows the science of DNA to predict (nothing is an absolute!) who your ancestors might be.
