From the paper:
In conclusion, the ancient distribution of the Y1 and Y2 haplotypes suggests that they do not discriminate European and Near Eastern Y-chromosomal lineages. As a consequence, there is still no patrilinear marker for investigating possible male introgression between imported cattle and European aurochs. So far, the importation of taurine cattle from its Near Eastern centre of domestication into Europe without subsequent hybridisation with local wild cattle populations remains the preferred model for the origin of European cattle.
From this paper, Figure 1 has the "Assumed distribution of aurochs mt-haplogroups in Western Eurasia", Figure 2 has the ancient Y data.

Y-SNPs Do Not Indicate Hybridisation between European Aurochs and Domestic Cattle
Ruth Bollongino et al.
Previous genetic studies of modern and ancient mitochondrial DNA have confirmed the Near Eastern origin of early European domestic cattle. However, these studies were not able to test whether hybridisation with male aurochs occurred post-domestication. To address this issue, Götherström and colleagues (2005) investigated the frequencies of two Y-chromosomal haplotypes in extant bulls. They found a significant influence of wild aurochs males on domestic populations thus challenging the common view on early domestication and Neolithic stock-rearing. To test their hypothesis, we applied these Y-markers on Neolithic bone specimens from various European archaeological sites.
Methods and Findings
Here, we have analysed the ancient DNA of 59 Neolithic skeletal samples. After initial molecular sexing, two segregating Y-SNPs were identified in 13 bulls. Strikingly, our results do not support the hypothesis that these markers distinguish European aurochs from domesticated cattle.
The model of a rapid introduction of domestic cattle into Central Europe without significant crossbreeding with local wild cattle remains unchallenged.
