WebHaplogroup L1 is one of the oldest branches of the maternal family tree, a daughter of the mitochondrial Eve and sister to L0. It is most frequently found in western and central sub-Saharan Africa, and seldom appears in eastern or southern Africa. L1 gave rise to branches L2–L6, with L3 giving rise to all the non-African haplogroups found today. WebAlthough mtDNAs from haplogroups A-to-D are often found together in a single population, many tribes lack haplotypes from at least one of these haplogroups.
