DNA Testing Sales and Deals

The more people that get tested, the more chances you have of ethnicity samples becoming more accurate, and the more chances you have of finding cousins.  If you have had your DNA tested, look back at the results a couple of times per year, you may find more accurate results just from more data being added from new testers. You will not have to pay again.
Or you can pay about $39 to have a DNA test from another company transferred to Family Tree DNA.  The more companies you test at, the greater your chances of having a match with a cousin. 
And information from YourDNAGuide.com about another free option to share your DNA tests.  Download your results to Gedmatch.com   to compare with more users.   GEDmatch provides DNA and genealogical analysis tools for amateur and professional researchers and genealogists. Most tools are free.  Read how to do it in the second part below:

National DNA Test Sales end today!

Vicki’s note – WOW – massive sale for everything DNA genealogy testing research!  Hurry – most end today April 26.  DNA testing sales will happen again around the Christmas Holiday season.  Also be looking to see if there is another National DNA Test Sales day (s) about April 21-25 next year.  I have been way busy lately and just saw notice of this very short sale from Thomas MacEntee:

5 First Steps to Researching Your Own Adoption

Vicki’s Note – article from Family Tree Magazine:

5 First Steps to Researching Your Own Adoption

11/28/2016

Simplify researching your adoption by taking these 5 easy first steps.

Trying to discover the identities of your own birth parents means navigating a maze of records access laws, genetic matches and family stories. Make sure you cover these 5 first steps to researching your own adoption as you begin your search:

1. Get a current copy of every bit of information the state where the adoption took place makes available.

You may have done this, but if it’s been more than a couple of years, do it again: Laws may have been passed making records more open. If the state allows access to your original birth certificate, get it. If a past request was denied, ask again, in case the laws have changed.

2. Review every scrap of information available within your adoptive family.

Review every letter, photo, postcard and memory for clues about the adoption and your biological parents. Ask questions of everyone who might have information and be willing to share it.

3. Take an autosomal DNA test at every testing company you can.

AncestryDNA has the biggest pool of test-takers, but don’t overlook 23andMe and the Family Finder test from Family Tree DNA. The right test for you is the test that puts you into the pool with a close family member—and you won’t know where that pool is until you dive into it.

4. Share your information on registries that cover the area where you were adopted.

Then search to see whether a member of your birth family may be looking for you. Many states (such as New York) have registries, and you can use websites such as Adopted.com.

5. Join online support groups.

Groups such as DNAAdoption and the DNA Detectives group on Facebook may be able to help you. Some can teach you more about DNA testing and how to build the kinds of family trees you’ll need to identify your genetic matches. Some can help you navigate record access issues or explain the confidential intermediary process. All will help guide you when it’s time to make contact with a possible family member.

Learning the DNA Lingo

Learning the DNA Lingo
4/6/2016
By Blaine T. Bettinger
Taking a DNA test for genetic genealogy research? We’ll help you understand some of the scientific terms you’ll come across.
Autosomal DNA (also called atDNA or admixture DNA): genetic material inherited equally from mother and father. It’s genealogically useful for ancestry back through about five to seven generations. Beyond that, you may not have inherited enough DNA from any one ancestor for that person to be represented in your autosomal DNA.

Centimorgan (cM): a measurement of the distance between genetic markers on the DNA based on the expected frequency of recombination with each generation. On average, one cM equals one million base pairs. In general, the more centimorgans you share with a genetic match, the closer your relationship (although individuals related through multiple ancestors also may share a high number of centimorgans).

Chromosome: a threadlike strand of DNA that carries genes and transmits hereditary information.

Genome: All the genetic material in the chromosome set of an organism. 46 chromosomes make up the human genome.

Genotype: The genetic makeup of a particular individual.

DYS (DNA Y-chromosome Segment): DYS followed by a number identifies a short segment of Y-chromosome DNA, also called a Short Tandem Repeat (STR) or a marker. A Y-DNA test reveals how many repeats of a particular nucleotide sequence are found at that DYS marker. For example, DYS390 is one of the most commonly tested Y-DNA markers, and values for the marker typically range from 19 to 28 repeats.

Genetic cousins: Individuals whose DNA test results match one another. You may have cousins who aren’t genetic cousins—that is, you and your cousin don’t match on DNA tests because you didn’t inherit enough of the same DNA from the same ancestor.

Haplogroup: a collection of related haplotypes with a common ancestor. The haplogroup (also called a clade) is usually defined by a single nucleotide polymorphism (SNP) mutation that arose in an ancestor hundreds or thousands of years ago, and is found in all of the descendant haplotypes.

Haplotype: an individual’s set of single nucleotide polymorphisms (SNPs) or DYS markers. Males who are recently related through their paternal line will have similar haplotypes and belong to the same haplogroup. The more diverse two haplotypes are, the more time has passed since their most recent common ancestor.

Mitochondrial DNA (mtDNA): genetic material both males and females inherit from their mothers. Because it’s passed down mostly unchanged from mothers to daughters, mtDNA can tell you about your maternal line—but because this type of DNA mutates infrequently, the results reveal only “deep ancestry,” not definitive links to recent generations.

Modal: the set of most-common DYS values in a group of closely related haplotypes. A particular branch of a surname, for example, might have a slightly different modal from another branch of the name.

MRCA (Most Recent Common Ancestor): the most recent paternal ancestor of two males. Every male on earth shares an MRCA with every other male, although some will have an MRCA thousands of years ago and others will have an MRCA within the last few generations. Y-DNA results can reveal how many generations have passed between two participants and their MRCA.

Mutation: a usually harmless change in the DNA sequence. A mutation can change the value of a DYS marker, for example. Although mutations are random, they typically occur at a known rate and thus provide a rough molecular “clock” useful for surname studies.

NPE (non-paternal event): a break in the Y-chromosome line resulting from adoption, infidelity or another cause. NPEs (also known as non-paternity events or false paternity) can be detected by DNA testing.

Recombination: the exchange of DNA segments at conception. Due to recombination, you inherit less autosomal DNA from each generation going back in time.

SNP (Single Nucleotide Polymorphism): the mutation of a single nucleotide in the Y-DNA sequence. One of the nucleotides, represented by the letters A, T, C or G, replaces another at that location in the sequence. Haplogroups are defined by SNPs.

STR (Short Tandem Repeat): a repeat of a short nucleotide sequence on the Y-chromosome. The DYS390 marker, for example, is an STR with between 19 and 28 repeats of the short nucleotide sequence. Closely related males will have a similar number of repeats.

TMRCA (Time to Most Recent Common Ancestor): an estimate of the amount of time between two males and their most recent paternal ancestor, calculated using differences between the two haplotypes.

Y-DNA: genetic material passed down from father to son. Because surnames also pass from father to son, Y-DNA tests can confirm (or disprove) genealogical links through a paternal line.

Planning to add genetic genealogy to your family history research strategy? Or have you already taken a DNA test with Ancestry DNA, Family Tree DNA, 23andme or another company? Visit Family Tree University to find convenient, online genetic genealogy classes to help you choose the right test for your needs, analyze your test results, and use your results to answer questions about your family tree.
