For genealogical purposes, there are three main types of DNA tests that are available: Y-chromosome (Y-DNA) tests for the direct paternal line, mitochondrial DNA (mtDNA) tests for the direct maternal line, and autosomal DNA (atDNA) tests for finding matches on all your ancestral lines.
Those new to DNA testing for genealogy will soon become aware of GEDmatch. Common questions asked in genetic genealogy groups once a member receives their autosomal DNA results include: "How do I upload my raw data to GEDmatch?", "How do I use GEDmatch once I have uploaded?", and "What does it all mean?".
Robert ‘Bob’ Taylor was almost 10 years old when he was called to the office of the Catholic orphanage where he lived in Salford, Lancashire, England. He was told that his full name was Robert Bernard Taylor, that his date of birth was 12 September 1939, and that he needed to memorise these details.
When there are sales or discount voucher codes available for the purchase of DNA tests for genealogy, I share them here. If you are looking for Christmas gifts, current DNA test prices are at an all time low for the pre-Christmas sales!
Beginners to DNA testing for genealogy often ask how they can educate themselves to more easily understand the terminology, the science, the testing products and their DNA results.
Thousands of genealogists have tested their DNA for family history purposes, but from my experience it seems that many are not members of DNA Interest Groups (DIGs) or even family history societies - they are going it alone, or getting their support entirely online.
When you test your autosomal DNA, your X-DNA is also examined and included in your raw data &/or match results. When you match someone on your autosomal DNA and also share segments on the X-chromosome, the unique inheritance pattern of X-chromosomes can help isolate your common ancestor to particular lines of your ancestry.
Family Tree DNA's Autosomal Transfer Program is a very popular method of getting your DNA into the Family Finder database. Why wouldn't it be? It is free, quick and easy! When I have transferred AncestryDNA raw data files into FTDNA, I have been able to access the match results very quickly.
Once you start taking an interest in DNA testing for family history purposes, you will naturally want to find out more about how everything works - the test types, who to test, choice of testing companies, understanding results, taking it further, support groups, online forums, advanced tools, projects, etc.
