qnli question: The founder lineages were likely from what type of mtDNA pool? sentence: In 2006, a study by Behar et al., based on what was at that time high-resolution analysis of haplogroup K (mtDNA), suggested that about 40% of the current Ashkenazi population is descended matrilineally from just four women, or "founder lineages", that were "likely from a Hebrew/Levantine mtDNA pool" originating in the Middle East in the 1st and 2nd centuries CE.
