Genetic studies on Ashkenazim have been conducted to determine how much of their ancestry comes from the Levant, and how much derives from European populations. These studies—researching both their paternal and maternal lineages—point to a significant prevalence of ancient Levantine origins. But they have arrived at diverging conclusions regarding both the degree and the sources of their European ancestry. These diverging conclusions focus particularly on the extent of the European genetic origin observed in Ashkenazi maternal lineages.
Output:
Genetic studies on Ashkenazim have found a significant prevalence of what type of origins?
