Learning about Genetic Genealogy: Conferences, Courses, and more


Cece Moore
If I were just starting to learn about genetic genealogy now, I think I would sign up for the Institute of Genetic Genealogy’s conference in Washington this August organized by two of the leaders in this new field: Cece Moore (pictured to the left) and Tim Janzen. Immersion always works best for me.

If I could not make that, then I would try DNA day at the Southern California Genealogical Society Jamboree in June.

In the meantime I might attend the Google+ hangout from 23andme Genetic Genealogy Basics, on May 22 at 12PM PST (3PM EST) (details at http://throughthetreesblog.tumblr.com/post/85927430757/hangout-with-23andme-genetic-genealogy-basics )

Then there are also a number of online courses to take:

Klotho – a gene for longevity and better brain function as you age

A recent discovery in the news is the Klotho gene which seems boost brain function and adds to longevity. About one in five people have the good variant.

KLsnpIf you tested at 23andme, you can find out if you have it by checking the SNP at rs9536314, the protective variant is the heterozygous one, GT, while the normal variant is TT. The homozygous version, GG, appears to be deleterious.

So log into your 23andme account and then click this URL to see if you have the GT  version is

Here are a few informative news articles explaining this discovery:

The myOrigins feature at familytreeDNA

Family Tree DNA has come out with a great way of showing your genetic ancestry for the last several thousand years using a clickable feature-filled map called “myOrigins.” It is listed in the submenu under “Family Finder” on the main menu. You have to have done the Family Finder test, or transferred your autosomal data from elsewhere, to have this feature.

Their data shows that DNA has specific signatures in geographic clusters rather than by modern countries, so your origins are shown in terms of those clusters. In my own case, I am half Norwegian from my Dad and half German from my mother where half of that German was Jewish. I know from other testing companies that I got well more than 25% of my jewish grandfather’s DNA, so I was not surprised to see Jewish Diaspora listed at 32% as 23andme says I have 27% Ashkenazi. Here is the myOrigins picture for me from my transferred 23andme data.

My Genetic Heritage as shown in myOrigins at familytreeDNA

The bottom left box shows your relatives’ percentages in your top three clusters. You can click on any relative to show the location on the map for their furthest back maternal and paternal ancestor (if they have entered that information). Clicking the green (maternal) and red (paternal) dots on the far bottom right will put pins on the map for the furthest back maternal and paternal ancestor locations for all your closest matches who have entered that information. Click on a pin to see the person’s name. Click the red or green dots again to get rid of those pins.

To see a little historical explanation of a specific population cluster you have to expand the larger cluster, for example European, in the box on the top left, and then click on a specific cluster like “European Coastal Plain.” Then some information will be displayed in the bottom left box, under the “My Ancestry History” tab.

Here is part of what it says about my Northlands cluster, “The European Northlands centers on the people of Scandinavia. They thought of their homeland as an island because it is relatively isolated from the rest of the world by the Baltic and other seas. This isolation and later association with the Finnic peoples, however, have changed them in ways that are genetically clear. A sister cluster to European Coastal Plain and European Coastal Islands, the European Northland has developed in moderate seclusion, influenced by the arctic heritage it shares with those from the North Circumpolar cluster.” Since I am shown as well more than half Northern, I have to assume some of that came to my German side as well.

To better understand how to use all the features, I did the online seminar about myOrigins which can be found at the ftDNA library of webinars located at https://www.familytreedna.com/learn/ftdna/webinars/. It was easy to sign up for it and download it and then play it in the “Windows Media Player” where it worked perfectly.

The new Y tree at Family Tree DNA and our Munson R-P312 Y

MunsonNewYThe new Y tree released this past week by Family Tree DNA has dropped all those horrible long names like R1b1b1a1 and replaced them with the main Y  haplogroup followed by the terminal SNP. This had long been suggested as a better nomenclature. The downside is that you have to look at a chart to see how an R-P311 might be related to an R-P312 but it is worth it for the simplification of the name. Although I think we R1b’s are used to being different from the R1a’s and I would prefer that we were R1b-P312

The new Y tree combines the research of Family Tree DNA and the Genographic project.  The press release and its highlights are published on Emily Aulicino’s blog:

and Debbie Kennett’s blog goes into deeper details:

http://cruwys.blogspot.com/2014/04/the-new-2014-y-dna-haplotree-has-arrived.html

 

But what does this mean for us R1b Munsons? Are we Scottish or Germanic? Where did our earliest known paternal line ancestor, Mons Knutson Titland  1665-1725 , who farmed a little north of Bergen, come from? Does our Y DNA tell us?

Celebrating DNA day!

DNA Double HelixSixty-one years ago today according to the Wikipedia article on DNA Day,  “James Watson,Francis Crick, Maurice Wilkins, Rosalind Franklin and colleagues published papers in the journal Nature on the structure of DNA.” As I am sure you all know, understanding the double helix nature of DNA was a major break through, paving the way for the multitude of amazing discoveries since.

Fellow blogger and genealogy junkie Sue Griffith has detailed the DNA day sales on her blog so I won’t repeat that information here.

So how to celebrate? I know, blow off work and spend the day doing my personal genetic genealogy when not in the garden 🙂
