ancestryDNA​ new (at least, to me) features

I'm probably just being dense here, - but what do the cms and strands actually denote?

I've just noticed that they've now added the shared DNA in the general listing of matches  - a great help compared with having to click on the info (i) button.

It wasn't there last night.

snip eg:

A good improvement - also if you now click the ? you get a guide as to what centimorgan amounts may mean. Perhaps there should be a caveat that there are sometimes extreme outliers.

Ahh, - thanks, I hadn't clicked on that!

What on earth is an 'extreme outlier'?

What it sounds like . You may have a much higher centimorgan match for a much more distant ancestor than is included in those ranges or a much smaller one for a close relative due to the random nature of DNA inheritance.

The ? has always been there but only when you selected an individual match.

***Outliers are the cases that deviate from the 'best fit line' of a scatter diagram (regression analysis, etc. )

Thinking about it, I think melba was using outlier to mean those at the extremes of a range rather than in the Statistics sense of deviating from the line of best fit.

The centimorgans are the most important.  For instance the centimorgans of my son are 3425 (not 2425 as I put originally, a cousin's daughter 423, my half 2nd cousin once removed 66, however, Ancestry shows her as my 4th cousin as the average number of centimorgans is similar for half 2nd cousin once removed and 4th cousin.  Obviously, if I hadn't already known this person I could have got confused trying to find a 4th cousin who didn't exist.

There is a shared centimorgan (Cm) Project with charts showing the relationships etc.  if you go to:

some of you may find the information interesting.

I think your link is wrong Lizzie. It just has

and a whole page of code   -see snip


If you look at my earlier post #34,  you'll see that we were talking about cMs
