Yamnaya and Bell Beaker drift and ratio in present-day Europe

Following statistics gives an insight into how the Bronze Age Steppe ancestry transforms to a modern Northwest European genetic model and gives an idea of differences seen in Europe today.   I made free tests:

f3(Yamnaya Samara, X: Ju_hoan North)
f3(Bell Beaker Germany, X: Ju-hoan_North)
dstat(Bell Beaker Germany, Yamnaya Samara: X, Ju_hoan_North)

All results are based on around 450000 SNP's.

Results of F3_statistics were standardized to a common value 1 and also dstat-results were standardized separately to value 1.  The results show that a Yamnaya type ancestry is still significant in East Europe and the turning line from Yamnaya to Bell Beaker goes from Western Finland to Lithuania and Belarusia.   European farmer or Middle Eastern ancestry becomes dominant in South Europe leading to decreasing Bell Beaker ancestry in absolute terms.
