A 2011 mitochondrial DNA study focused on maternal ancestry sampling 41 Beta Israel found them to carry 51.2% macro-haplogroup L typically found in Africa. The remainder consisted of Eurasian-origin lineages such as 22% R0, 19.5% M1, 5% W, and 2.5% U. However, no identical haplotypes were shared between the Yemenite and Ethiopian Jewish populations, suggesting very little gene flow between the populations and potentially distinct maternal population histories. The maternal ancestral profile of the Beta Israel is similar to those of highland Ethiopian populations.
