DNA Logic Puzzles

My Dad always loved the Logic puzzles in the Dell Puzzles Magazines. As I'm working on DNA matches today I can't help thinking about him.  Not just because I am working on my paternal matches but that he would like the logic I am using.  While I have had my DNA results and those of my Mom for over a year, my sister's results came in not long ago and we now have her kit at GEDmatch. She is a full sibling but there seems to be a good variation in the people which we match due to the randomness in the 50% which you get from each of your parents..  What does that mean for me? I can take her it with Mom's to phase out Mom's matches and create a kit of Sis' DNA she got from Dad...which I can then compare to my DNA which I got from Dad.  If I know that one of us matches Dad's Mom along one segment..and it's a segment that we don't match along....I then know that the other one of us matches Dad's Dad along that segment which we don't have in common.  After all...Dad only had two to you got one or the other.

An Example:
Chromosome 4 on my Paternal side(which I can see by using the phased kit) I have a section from about 4-40 which I know I can attribute to my Paternal Grandmother's  Morrow/Sutton lines. My Sister has NONE of these same matches along that same segment of her Paternal side(I can again distinguish her Paternal from her Maternal matches by using the phased kit of her DNA she got from Dad mentioned earlier).  By this I can conclude that the matches along that segment for her are from my Paternal Grandfather's side and somewhere back along the Cook/Putman or King/Manire lines.

While this won't solve all of my unknowns, it is a big help in knowing where to look for the connection for these matches. So many times I wish that the matches had some idea of which side I match them along.This is one of the greatest things about having a parent and a full sibling that have also tested.

Visual representation of Chromosome mapping

This is my daughter Brittany's Chromosome map. She and I both have done the autosomal test as have her maternal grandmother and paternal grandmother.

In addition to her grandmothers testing she has a maternal aunt and a paternal uncle who have also tested as well as several Paternal Great Aunts & a Great Uncle.  This will help to sort thru her matches.

MGF--Cooke/King  & Jakes/Frizzell
MGM- Acuff/Hale & Luna/Pittman
PGF- Beckman/Folley & Harper/Mattox
PGM-Mosley/Hogland & Demonia/Brantley

This segment map is a screenshot from the GenomeMate Pro program which I use to help track my matches for kits I manage.

AncestryDNA's new update: Before & After comparison using my kits

After 2+ weeks without matches to my AncestryDNA kits and waiting on my sister's kit to finish processing the results are in.  As I logged on shortly after lunch today I saw this message and started seeing my sister as a match in the kits I manage.

I have several kits at AncestryDNA:  Mine, My Mom's kit and my Daughter's kit.
I made note prior to the changes of the amount of Hints, 4th Cousins & Greater, DNA Circles, New Ancestor Discoveries and pages of matches each of the kits had.  The chart below shows a comparison.  I did expect the amount of circles to decrease as some people fell out of the match range. My sister's kit had no data prior to the roll out as it had not processed.

Now I am hoping to get her kit to GEDmatch.  Have you tested at Ancestry?  How did yours compare?
