From a post by Robert Clark on the ISOGG FB Page
"A little news for AncestryDNA customers: At the American Society of Human Genetics conference, I spoke with Cathy Ball, Chief Scientific Officer for Ancestry. Among other things, I asked her about the lack of a chromosomal browser for AncestryDNA. She explained to me at length that Ancestry has many improvements in the works, but a chromosomal browser is not one of them. She said there are 2 main reasons for this:
1) Privacy issues - sharing potential DNA loci with relatives would grant knowing disease-associated loci to relatives to whom you are sharing your DNA information, and
2) "bad science" - people often misuse their shared loci information and infer that shared population-wide loci gives proof for closer relations than are true.
Please don't shoot the messenger, as I am relaying what she told me. So, back to GEDmatch for me."
I agree Robert back to GEDMatch so I can look for CB info for my Ancestry matches.
