My Analysis of Motala-12 ancient DNA

The Motala samples come from the site of Kanaljorden in the town of Motala, Östergötland, Sweden. The site was excavated between 2009 and 2013. The authors state that these samples are between 7,013 and 6,701 years old. I converted the raw data supplied in this scientific paper to formats familiar with genetic genealogists. I also filtered with SNPs tested by DNA testing companies like FTDNA, 23andMe and Ancestry in order to upload to GEDMatch but found this ancient DNA has less SNPs that are common with them except Motala-12. Hence, I am not uploading the rest to GEDMatch. Motala-1, Motala-2, Motala-3, Motala-4, Motala-6, Motala-9 and Motala-12 are available for download. Motala-12 is uploaded to GEDMatch as kit# F999917

Admixture

Because this sample is European, I went ahead to use the Eurogenes calculator.

There is a 0.75% if Amerindian in Motala-12 sample.

Y-DNA

The Y-Haplogroup corresponds to I-L460 (I2a). However, some SNPs for positive and some are negative for I2a1b, which may suggest a new lineage from I2a1b.

Y-STR

  • DYS617 = 12
  • DYS385a/b = 14
  • DYS460 = 10
  • DYS464a/b/c/d = 15

LobSTR reports the above Y-STR values. Based on my experience, it may be off by 1.

Mt-DNA

Mt-Haplogroup is U2e1, which is same as Motala-2 and Motala-3 samples.

Parents Related?

Runs of Homozygosity reveals the parents of Motala-12 is not related to each other.


Comparison

When I compared Motala samples with each other using the entire unfiltered SNPs, I wasn't able to get any good segment matches, probability due to lack of SNPs. But I did get one significant match between Motala-12 and Motala-3. 


Chr     Start Position  End Position    Len(Mb)        SNPs
4 10259 14393451 14.3832 873

Largest Segment: 14.3832 Mb
Total Shared: 14.3832 Mb

The above match is significant because, the thresholds used is 7 Mb / 700 SNPs allowing no error SNPs. So, Motala-3 is related to Motala-12 in it's genealogical timeframe. 

The sample is tokenized in GEDMatch and available for 1-to-1 comparison. Please wait for 2 days before 1-to-many comparison results are available. Let me know what you find.
