Mal’ta MA-1 Ancient DNA Analysis

After processing the Mal’ta MA-1 Ancient DNA sample,  I proceeded with the output data to see what I can find.

Haplogroups

The Y-Haplogroup is R,  but also positive for R1b1a2a1a2c1b4 (or R-CTS3087). The mtDNA is U, but also has defining mutation for K2a5, U5a1, U1a'c, K1b1 and U6a3a1. Hence, the Y-Haplogroup is R and Mt-Haplogroup is U.

Y-STR

LobSTR reports the following Y-STR values.

  • DYS458 = 16
  • DYS425 = 10
  • DYS462 = 12

Based on my experience, the actual Y-STR may be off by 1.

Telomere

The kit also has a telomere length of 4.7174 which may suggest the boy's age was roughly around 10-15 at the time of his death.

Autosomal

I uploaded to GEDMatch as #F999914.

Based on MLDP K23b calculator,

MLDP K23b admixture for Mal'ta Boy
I am surprised at 4.5% of South Indian admixture which interests me. So, I proceeded with HarappaWorld.

HarappaWorld admixure for Mal'ta Boy
HarappaWorld places 10% of South Indian admixture.

I am waiting for batch processing to complete, but you can proceed with one-to-one comparison. I did with mine and nothing significant. I don't expect anyone to match because it is an ancient sample but there may also be surprises. Let me know what you find.
