My focus is autosomal DNA as most of these links will reflect.
Before you jump into the deep end of the gene pool, read this:
Succeeding with autosomal DNA (atDNA) - a rootsweb post
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
Update from March 21 meeting:
George has shared these weblinks pertaining to yDNA testing with us. We sure appreciate the time he spent sharing with us!
"Thanks for inviting me to speak with your
Genetic-Genealogy SIG last Tuesday evening at the WELL.
During the course of our conversations and questions, I
mentioned several different web sites that your members might find useful. I'd
like to provide links to those sites to aid your members with their
research. I will group them below in no particular order.
DNAeXplained Blog by Roberta Estes:
Roberta Estes makes regular post to this Blog explaining how
she uses DNA tests to help with her search for her ancestors. Roberta is very
good at breaking down the often complex ideas behind genetic Genealogy and
explaining it in simpler everyday terms (hence, the name)
McGee's Genetic Distance Tool by Dean
McGee:
Dean McGee developed this tool years ago for use in his
McGee Surname Project and he has made it available to use by the public for
free. There are instructions on the page for how to use it, but in a
nut-shell, the user inputs the Y-STR values for 2 or more individuals and then
runs the tool. The result is a matrix which provides a graphic display of the
likelihood of relatedness between the individual entries, and the approximate
time-frame back to their Most Recent Common Ancestor (MRCA).
I now see that there is also a YouTube Video that explains
how to use the tool. I have not actually looked at this video, but here is the
link to that video. https://www.youtube.com/watch?v=wEvsRpRv-SI
DNAAdoption for folks with questions about
using DNA to help locate their birth family:
This site, and the guidance they provide for adoptees, has
proved very useful lately and has even helped solve a cold case of a girl who
was found abandoned years ago by a person who, it turned out, had kidnapped her
after murdering her parents. The tool and methods laid out for use by Adoptees
can also be used to help figure out cases of NPE's.
Carol Schweitzer, Mentioned in this article, spoke about the Cold
Case at the International Genetic Genealogy conference in Houston last
November. By the time she finished her tale we were so amazed that you
could have heard a pin drop in the room with almost 300 attendees.
ISSOG The International Society of
Genetic Genealogy:
For those who just "geek out" over Genetic
Genealogy, this site might be for you."

Blaine Bettinger DNA series offered by Legacy Family Tree Webinars:
This series was released sometime last week. It is a series of 5 lectures designed beginning student of DNA. It is perfect for those looking for a review or a chance to enhance their basic understanding of DNA and genetic genealogy. I just watched the autosomal lecture (#5) and it dovetails nicely with what he covered on Saturday.

One caveat, this is a subscription site. You can subscribe by the month ($9) or by the year ($49) and watch all the webinars you want. I guarantee that it will be some of the best genealogy money that you spend. I have learned so much watching Legacy Webinars weekly. You can also watch a changing subset for free if you want to see what the site is all about. I think you will find it a useful investment of your time and money. (* Not affiliated, just appreciate the education value.)

From the meeting on August 9:
Autosomal DNA Segment Analyzer Manual from DNAgedcom. Mid-way down the page is an in-depth explanation of the ICW matrix (that colorful quilty looking part in the middle). This should help make its purpose more clear.

Facebook groups for learning-
If you are on FB anyway, these are good. If not, these groups may be worth signing up for, so you can follow them. I have learned a lot by reading and following other's dna problem solving.

My favorite posts from Jim Bartlett's segmentology blog:
Getting Started with Autosomal DNA Part I
What is a segment? –Ancestral(true) Segments vsShared(computer) Segments
Measuring Segments–bp(or Mbp);cM;SNP
Segments:Bottom-Up
Segments:Top-Down
How To Triangulate:Collect,Arrange,Compare/Triangulate
Anatomy of a TG (triangulation group - your matches and how you relate to each other)
Jim's ultra in depth spreadsheet he uses to keep track of all his matches. He definitely takes it to the next level here. This is all way above my head and I am just saving it here for reference. No way am I ready to process this much yet.
-- Thanks, Jim, for reaching out to me for research and being a cousin (even just a little tiny bit.) You have taught me so much in a short time.
My spreadsheet lite instructions (based on what I learned from Jim's How to Triangulate blog):
- download match spreadsheets from testing sites or from Gedmatch*, copy/paste the segment matching list from your comparison into excel.
- clean up and freeze the top line ( under view menu)
- sort by start point, then Chrom #
- you can convert the bps to megabps for easier reading (format cells>number>custom> type "0.00,,"). Do this to start and end columns.
- filter out smaller matches (set filter on cM column to show matches greater than 10)
- add data bars to start and end to show triangulation matching groups (highlight column > conditional formatting>data bar, choose solid)
*to get a usable chart (for our group purposes) from gedmatch-
-choose your closest (or any close) match and run a "matches 1 or both" search. Your results will generate 3 charts.
-From the chart that matches both, select top 10 to 20 (max) matches.
-Copy/paste the entire resulting chart into excel.
-From this point revert to the 1st set of instructions to complete your excel match spread sheet.
