They have added a new feature (aka another DNA diagnostic tool) to the Ancestry DNA match page.
Now when you open a match you will get the total amount of shared DNA with your matches in centimorgans (cM) and how many segments that DNA occupies. So again they are slowly advancing the ball towards a chromosome browser IMHO.
Below is a screen capture of what I saw for my dad's match with me.
This feature works on every match on your pages including private trees, unlinked trees, no linked trees, leaf matches, etc.
Now how accurate is it, that remains to be seen. CU you all in class Tuesday night and hope to have more in the pre class show.
Here is the information page from Ancestry on this feature which is tied to the match confidence level.
What does the match confidence score mean?
When we compare your DNA to the DNA of one of your matches, we calculate a confidence score for you. This score lets you know how much DNA evidence there is for you and your match actually being related.
But, just because you and another member have identical DNA doesn’t mean that you both inherited that DNA from a recent genealogical ancestor. (Learn how you can have identical DNA and not be related.) That’s where the confidence score comes in, and how we calculate the likelihood that you and your DNA match are actually related. A high confidence score means that we’re pretty sure that your DNA is identical because it was inherited from a recent ancestor. A lower score means that your identical DNA might be because you’re related, but it might also be because you have similar ethnic or regional backgrounds.
The confidence score is based on the amount and location of the DNA that you share with your match. We show the shared amount using centimorgans (cM), a unit used to measure the length of DNA. The higher the number, the higher the confidence, and in general, the closer the relationship. Since you can share DNA with your match on one or more segments in different locations in the genome, we show you how many. Note that the number of segments and number of centimorgans that we show reflects only those segments that we believe were inherited from a recent common ancestor (in other words, segments that are likely to be identical by descent).
When you’re exploring your list of DNA matches, look for these confidence scores and let them help you focus your research.
Confidence Score / Details
Extremely High - Approximate amount of sharing: More than 30 centimorgans
Likelihood you and your match share a single recent common ancestor (within 5 or 6 generations): Virtually 100%
You and your match share enough DNA to prove that you’re both descendants of a common ancestor (or couple)--and the connection is recent enough to be conclusive.
Very High - Approximate amount of sharing: 20—30 centimorgans
Likelihood you and your match share a single recent common ancestor (within 5 or 6 generations): 99%
You and your match share enough DNA that we are almost certain you’re both descendants of a recent common ancestor (or couple).
High - Approximate amount of sharing: 12—20 centimorgans
Likelihood you and your match share a single recent common ancestor (within 5 or 6 generations): 95%
You and your match share enough DNA that it is likely you’re both descendants of the same common ancestor or couple, but there’s a small chance the common ancestor(s) are quite distant and difficult to identify.
Good - Approximate amount of sharing: 6—12 centimorgans
Likelihood you and your match share a single recent common ancestor (within 5 or 6 generations): More than 50%
You and your match share some DNA, probably from a recent common ancestor or couple, but the DNA may be from distant ancestors that are difficult to identify.
Moderate - Approximate amount of sharing: 6 centimorgans or less
Likelihood you and your match share a single recent common ancestor (within 5 or 6 generations): 20—50%
You and your match might share DNA because of a recent common ancestor or couple, share DNA from very distant ancestors, or you may not be related.
It’s important to note that the confidence score is related only to your match and not to the relationship range we’ve assigned. The confidence score should not be interpreted as our confidence that you are specifically 4th cousins, for example. Instead, it lets you know how confident you should be that you and your DNA match are related through a recent common ancestor.
