Abstract
The third millennium BCE was a pivotal period of profound cultural and genomic transformations in Europe associated with migrations from the Pontic-Caspian steppe, which shaped the ancestry patterns in the present-day European genome. We performed a high-resolution whole-genome analysis including haplotype phasing of seven individuals of a collective burial from ~2500 cal BCE and of a Bell Beaker individual from ~2300 cal BCE in the Paris Basin in France. The collective burial revealed the arrival in real time of steppe ancestry in France. We reconstructed the genome of an unsampled individual through its relatives’ genomes, enabling us to shed light on the early-stage admixture patterns, dynamics, and propagation of steppe ancestry in Late Neolithic Europe. We identified two major Neolithic/steppe-related ancestry admixture pulses around 3000/2900 BCE and 2600 BCE. These pulses suggest different population expansion dynamics with striking links to the Corded Ware and Bell Beaker cultural complexes.​

Interesting to have DNA from what seems to be a non-elite burial of Bell Beaker people.
The males have admixed steppe ancestry and Y-DNA R-L151.
The females lack steppe ancestry.
 
In the supplementary information there is a table (S11) with more detailed information about the y-haplogroups.

Bre445HI is not on that table but the study says “FK and HI shared the same Y-chromosome haplotype R1b-L151, suggesting, given their ages at death, that they could be biological father and son.”, so Bre445HI must be also R-U106.
 
R1b1a1b1a1a1c1a2a1 is R-A7108 (ISOGG 15.73), formed 2500 ybp.
It is strange that they have assigned such detailed haplogroup to individuals from the third millennium BCE, ~2500 BCE or 4450 ybp.

indeed something is wrong here
