This was presented by Dr David Reich last weekend so there should be a paper coming out shortly.
About 4,500 years ago they arrived in Britain, replacing 90 percent of the gene pool, possibly as a result of the diseases they brought and climate change. But on the Iberian Peninsula, something more dramatic took place.
It appears there was some sort of “violent conquest”, notes New Scientist, where local males were either killed or enslaved and the females claimed by the Yamnaya. This is evidenced by a “complete Y-chromosome replacement,” according to Reich. In other words, Spanish men disappeared completely from the gene pool.
Other research has also highlighted the dramatic shifts in population as a result of the Yamnaya arriving. It’s thought that they replaced half of Europe’s genetic ancestry within a few hundred years, with a study last year suggesting 10 men for every one woman migrated into Europe as part of the group – an “extreme” ratio.

That is pretty extreme. It wasn't exactly Yamnaya either as stated above but Bell Beakers. Looking forward to the research being published. If anyone has more details please post or discuss here.
