Visual Phasing: An Example (Part 5 of 5)

Five-Part Series on Visual Phasing:

In “Visual Phasing: An Example (Part 1),” we identified and labeled all of the recombination points in the three siblings, Susan, Brooke, and Felix. Then, in Part 2 of the series, we used the identified and labeled recombination points to assign segments of DNA to the four grandparents (the blue grandparent and grey grandparent pair, and the purple grandparent and green grandparent pair). In Part 3 of the series, we used cousin matching to identify the grandparental source of the chromosomal segments. And finally, in Part 4 of the series, we characterized my paternal chromosome.

After Part 3, we had the following for Brooke, Susan, and Felix:


Now that we have this information, let’s see if we can use that to explore new matches with Brooke, Susan, and Felix. ... Click to read more!

Recreating a Grandmother’s Genome – Part 2

In my last post (see “Recreating a Grandmother’s Genome – Part 1”), I introduced my grandmother Jane, who died when I was just 8 years old. Although I have only a few memories of my grandmother, I have 25% of her DNA. To explore this rich genetic legacy, I’m trying to recreate as much of my grandmother’s genome as possible using the GEDmatch Tier 1 tool called “Lazarus.”

In the last post we also learned about the new Lazarus tool. In today’s post, we’ll choose what kits to use for my grandmother’s Lazarus kit.

Finding DNA Kits for Lazarus


So GROUP 1 must be descendants of the target Lazarus kit. My grandmother has six children, twelve grandchildren, and eleven great-granchildren. Any of these 29 people are candidates for GROUP 1. Of those 29 people, I’ve tested four of the six children and one of the grandchildren (myself). Yeah, I know, I have more testing to do! ... Click to read more!

Recreating a Grandmother’s Genome – Part 1

My grandmother Jane died in 1984 when I was just 8 years old. I have some really great memories of her, faded with time but still filled with emotion. Bath times, spending time with her in the summer, newspaper hats, chrysanthemums.

However, in addition to those memories, she gave me a very unique genetic heritage. She was from a region of the world with a high degree of admixture, and thus it is from her that I obtained my Native American mtDNA, my Native American, African American, and Spanish autosomal DNA. It is an incredibly rich and fascinating genetic legacy.

In an attempt to learn more about my grandmother’s genetic heritage, I’m using GEDmatch’s new Lazarus tool to try to recreate as much of her genome as possible. Join me on the journey, and learn about this new tool. ... Click to read more!

Finally! GEDmatch Announces a Monetization Strategy (and a Way to Raise the Dead?)

GEDmatch   Tools for DNA and genealogy researchIf you’re serious about genetic genealogy, you’ve heard of GEDmatch. The third-party site is one of the few ways to compare testing results among the three testing companies. The site

However, since GEDmatch is run by two incredible volunteers (Curtis Rogers and John Olson) with full-time jobs, the site has experienced server issues and downtime. Many have lamented that there was no monetization plan in place, but gave donations in hope that it would help the site grow.

This week, GEDmatch announced a monetization strategy, namely advanced tools that are only available to Tier 1 members at a nominal cost of $10/month:

Basic GEDmatch programs remain free and we plan to keep them this way. Donations help cover the costs associated with running this site, and will provide you with the benefit of using the additional Tier 1 tools for a period of time equal to one month for every $10 donated. You may use the ‘Donate’ button below, for a one-time donation of any amount, or the ‘Join GEDmatch’ button to establish a recurring $10 per month amount. ... Click to read more!


Is your group interested in learning more about DNA testing and how it can be used in your genealogical research?  Or are you curious about the intersection of genetics and history?  I lecture all over the United States, Canada, and several other countries to groups of all sizes and experience levels, and I’d love to speak to your group. Below are some of the lectures I provide.  Each lecture is a stand-alone talk, but they can be mixed-and-matched for a full-day workshop.

Day-Long Programs

I’d also like to provide suggestions for day-long seminars. Here are three different schedules ranging from introductory to advanced, but I can tailor a day-long program to the needs of your organization.
