LESSON 11: Deeper Exploration by Subject

There are a myriad of great genetic genealogists out in cyberspace, many with their own blogs. This is an outline of blog posts and websites on various topics that you may find helpful. Since my lessons are primarily geared to giving you an overview of what's out there in the DNA testing world I intend to point you towards reviews and lessons that speak to one aspect or another of the various products and how to use them rather than get bogged down in the details, since each persons' needs will very.

I do this for two reasons. One to conserve my own limited website space and two to avoid duplication of material already available. Please explore the links below for in-depth looks at each company's product(s) and how to use them and other tools or subjects listed. These are included because they have good visuals and commentary. This way you can explore the ones in which you are most interested.

Converting % of Genome to cM Source: Tim Janzen from Rootsweb AUTOSOMAL-DNA mailing list, 12 Apr 2014. 

"My extraction and interpretation from this: When using 23andMe data (autosomes + X-chr), divide the total cM by 74.4 for females (two X-chromosomes) and 72.6 for males (one X-chromosome) to get the percentage of the genome that two people share. In Build 37, per Family Inheritance: Advanced, there are 7438.6 cM when combining the autosomal DNA and the two X chromosomes in females and 7256.8 cM in males – and 7074.6 cM for just the autosomes.

When using Family Finder (FTDNA) data (autosomes + X-chr), divide the total cM by 71.6 for females (two X-chromosomes) and 69.6 for males (one X-chromosome) to get the percentage of the genome that two people share, or if just using the autosomes, divide by 67.7 (both sexes). There are 7158.06 cM when combining the autosomal DNA and the two X chromosomes in females and 6962.13 cM in males – and 6766.2 cM for just the autosomes."
