- The Ashkenazi bottleneck refers to a population bottleneck that occurred in the Ashkenazi Jewish population between 500 and 800 years ago12. This bottleneck was caused by a combination of violence and the plague, which decimated the Ashkenazi Jewish population by close to 90 percent2. As a result, most of the 10 million Ashkenazi Jewish people living today are related to a few hundred “founding individuals”2. The bottleneck led to much of the genetic similarity seen among modern Ashkenazim3.Learn more:✕This summary was generated using AI based on multiple online sources.
