Jewish Y-DNA among Poles

[Tomenable]

Poles have 1.3% of Jewish Y-DNA haplogroups (8 people with Jewish Y-DNA in a sample of 598).

Source: upcoming study about Polish Y-DNA which will be published in "Human Genetics" journal.

Seems to correspond with the autosomal presence of Ashkenazi Jewish DNA in Poles, though its rather on the higher end of the expected spectrum, which makes me wonder about the female side of things - which might be lower, rather?

Do they publish the yDNA assignments or make the raw data public? Because I have a couple of branch members from Poland, plus my father and I have Polish autosomal matches too.

The study is based on The Thousand Polish Genomes database and these raw datas are not publicly available:

As for yDNA assignments, maybe they will be published, I will ask about it.

Yes the mean AJ autosomal admixture seems to be just below 1% (although median is much lower than mean).

Let's hope that someone will write a similar study about Jewish mtDNA, because I'm also curious about this!

It would be great if anonymised yDNA data could be transferred to say YFull or the like, that would be a big win, even though I'm not sure about the cooperation of both sides. Thank you for asking for the assignment!

They did analyse the mtDNA:

In this study, we analysed whole genomes of 1222 Poles to identify and genotype a wide spectrum of genomic variation, such as small and structural variants, runs of homozygosity, mitochondrial haplogroups, and de novo variants.

So its rather about further analyses/publication.

Tomenable, I've been studying this for many years now. From the summary on page 133 of The Maternal Genetic Lineages of Ashkenazic Jews (2022):
"...multiple Ashkenazic maternal haplogroups (H3p, K1a1b1a, K1a9, K2a2a1, and L2a1l2a) exist among ethnic Poles as the result of Jewish conversions to Christianity..."

Later, ethnic Poles were found to belong to the Ashkenazic mtDNAs A-a1b3a1 and N1b1b1c, almost certainly from having Jewish ancestors. Possibly also the Pole in H7c2b.
