From ancestry's website:
"Our new AncestryDNA test uses some of the latest DNA autosomal testing technology as a more comprehensive way to find family across all lines in your family tree. So one test covers both sides—maternal and paternal—and is equally effective for both men and women."
"Also, the Y-DNA and mtDNA tests look at much smaller amounts of your DNA. For example, YDNA tests only look at about 40 locations whereas AncestryDNA comprehensively looks at the entire genome at over 700,000 locations, all with a simple saliva sample. 40 vs. 700,000? You don't need to be a scientist to see that this is a huge improvement."
On the surface, it looks to be a much more comprehensive test. But can I assume then that there is not a means to cross reference this test to the standard Y-dna test. And that to do a comparison with someone who has already taken the y-dna test, I would also have to do the y-dna test.
Thanks for any info,
