I saw a video titled "Spain, Portugal have Roman Italian ancestry" and in the video the guy believes we have upwards of 30-40% Roman DNA. His theory is based off of the closeness to a north italian cline on g25 plots, and that our roman is from north italia. But I do not agree. This seems to just be an algorithm overfitting because north italians are already close to Portuguese and Spanish in ancient admixture. Instead, I believe our Roman is imperial era (southern-central italian-like) it would explain why our cline jumps from basque-like to more southern and closer to north italian.
Anyone have any idea of how much of this roman admixture we have?
