Abstract in brief

  • The history of Portuguese crypto-Jews dates back to the Visigothic period, marked by persecution, forced baptisms, and the eventual emergence of crypto-Jews in Iberia, with significant events like the Inquisition and expulsions shaping their fate.
  • Genetic studies on contemporary Jewish communities from Iberia, especially from Portugal and Mallorca, reveal limited but intriguing data, such as shared female lineages between communities and unexpected genetic diversity, indicating complex historical interactions and resistance to genetic erosion.
  • Recent research efforts are focused on understanding the genetic heritage of these communities by analyzing both male and female lineages, aiming to build a dynamic reference model that integrates genetic data with historical context to better comprehend Iberian Jewish history.

Ambiguous with regards to the inference of Jewish ancestry and do not identify diagnostic patrilineal or matrilineal markers (…) appears to contradict that Iberian Jews succeeded in maintaining a genetic heritage of their own. https://t.co/KUJD4GJ6Vr / https://t.co/UiknzRIyUB
