The SAPDA ancestry program (Shared Ancestral Population Defining Alleles) detailed at https://eurasiandna.com/sapda-admixtur ... revisions/ Is now available at GenePlaza.com. Since this software was developed using a new approach, your results may differ from those obtained using the widely used AD...

I have posted my take on the recent paper " An Ancient Harappan Genome Lacks Ancestry from Steppe Pastoralists or Iranian Farmers" at https://eurasiandna.com/an-ancient-harappan-genome-lacks-ancestry-from-steppe-pastoralists-or-iranian-farmers-a-critique/ Earlier this month the much awaited Bronze A...

What I've noticed is that admixture percentages in the same calculators on GEDmatch and on yourDNAportal are very different. Something must be wrong with algorithms used by yourDNAportal. For example one user on Anthrogenica posted their K36 results from GEDmatch and from yourDNAportal. The differe...

Hi everyone, As we move closer to the SAPDA ancestry inference software becoming publicly available, I just published an article at https://eurasiandna.com/sapda-admixture-inference-updates-revisions/ highlighting some of its features and principles. An excerpt from the article: SAPDA SOFTWARE FEATU...

My husband's results. One of his great great grandfathers was black. He's 5-6%. We can better understand his results if you post how many markers he didn’t have calls for Ok here's the whole thing. We don't know who this great great grandfather is. It's an NPE on his mother's paternal line originat...

My husband's results. One of his great great grandfathers was black. He's 5-6%. rs6875659AG People with your genotype have one copy of this mutation that is indicative of African ancestry. rs1399090CT People with your genotype have one copy of this mutation that is indicative of African ancestry. r...

:lol: Good point! I guess that is a tad obvious :lol: Really, what I am trying to figure out is whether only three such alleles are significant in figuring out whether one has actual African ancestry, very old or more recent. My family are Southern colonials and have been in America since the early...

I show 2 matches. I am not aware of any African ancestry and show no current % on 23andMe or other commercial tests. However, I used to show 0.2% in at least 1 mode with 23andMe kit before one of their updates. rs1871332GG People with your genotype have two copies of this mutation that is indicativ...

I have 5. Not sure what that means. rs6586395AC People with your genotype have one copy of this mutation that is indicative of African ancestry. rs3825663AG People with your genotype have one copy of this mutation that is indicative of African ancestry. rs13335375CT People with your genotype have o...

Is it common that most people (European/Middle East origins) have 1 to several of these alleles or is there a greater meaning? That's what I wondering. The rs6601548CT allele has come up a couple of times already. Maybe it's something Europeans have inherited from deeper ancestry from Africa rather...
