Is this paper legit? The author used qpAdm to get 41% Levant DNA for Ashkenazim
The above link is to a peer-reviewed paper dated in 2025 that stated that Ashkenazim jews have around 41% LevantineIA DNA. I'm new to population genetics and have minimal knowledge so please clarify on its analytical rigor.
​
What's the usual range of Levantine DNA in full Ashkies on qpAdm using all the relevant reference populations? Is there Levantine overlap with Southern Italians? Is it fair to say around 40-45% max for them? Please clarify.
​
I also corresponded by email with Shai Carmi & Shamam Waldman, authors of the 2022 Erfurt study, 2020 Bronze/Iron age study & 2017 Xue et al. study about Ashkenazim ancestry proportions. They said none of the studies can be taken as canon for ancestry percentages & that in future studies, the Levantine portion could be higher too.
