what is mean BSD ?

BSD is Balto-Slavic drift source (it is a combination of WHG and EEF with some amount of EHG).

Looks like I have more BSD than either of my parents.

This is perfectly possible, but probably some of your mother's WHG found a way into BSD.
You are a complex mix of your parents. It is interesting how you acquired so much of Yamnaya from your mother.

A little too much for a noise.
Something East-Asian (in your case maybe Szekler-like from Transylvania?).

Me and Velislav are NW BG and I have noticed we both score similar weird stuff sometimes it's Chinese other times it's SE Asian and this time he scored Native Australian and Canadian(Eskimo?) and I scored SE Asian. Our recent steppe is probably Cuman while yours should be a mix of stuff, I have seen when I ran myself in the past the 1% east Asian turns into 2-3% Tatar so you probably have around 4-5% recent steppe but ph2ter can't add that type of reference because it's a BA calculator when this type of East Asian+Indo-Iranian+Siberian population didn't exist the closest thing would be in the IA.

BSD according to the calculator:

@ph2ter, According to one of your previous posts, is this BSD from the BA? Are you able to give BSD in the late IA, preferably just before the evolution of the Slavs, as in circa 300-500CE?

These BSD G25 values are based on Spiginas2 and Vatya_o G25 values. The calculation was done using basic components (EEF, WHG, EHG, Iran). In the process, I basically had extracted some minor Iran component from Vatya_o and Corded Ware component from Spiginas2. What was left was optimised by iteration. As a result this BSD component does not contain any Yamnaya. BSD could be interpreted as a population living somewhere in Belarus in BA times just before mixing with Corded Ware. According to this understanding it makes no sense to calculate a different BSD based on IA populations, because it certainly was developed already in Bronze Age (Spiginas2 and Vatya_o are from about 1800 BCE).

[Siegmund]

My mother's mother side is Cuman, so maybe that cause the Chinese in this case.

[mjaguk]

I have some distant Tatar ancestry on my paternal Baltic side. It often gets interpreted as pretty much anything Asian or even Native American. Sometimes it's Chinese in these calculators, and has even been Chinese in a 23andMe estimate.

[ph2ter]

After I made this PCA based on ancient north-Eurasian samples it is obvious that Balto-Slavic drift has HG source (the colours are according to the age of the sample, the pink are the youngest, the yellow are the oldest, orange -> yellow ->green ->blue ->pink ->red):



I made a new HG-BS profile extracting EEF ancestry from my last HG-EEF BSD profile.
Such profile on PCA falls exactly inside the Baltic HG cluster:
