Human genetics
Human genetics describes the study of inheritance as it occurs in human beings. Human genetics encompasses a variety of overlapping fields including: classical genetics, cytogenetics, molecular genetics, biochemical genetics, genomics, population genetics, developmental genetics, clinical genetics,...

, Haplogroup L4a is a human mitochondrial DNA (mtDNA) haplogroup. It is a small African haplogroup. It was once called L7 and considered its own branch of L. It was determined to be a subclade of L4 and renamed L4a by Behar et al. in The dawn of human matrilineal diversity.

Tree

This phylogenetic tree of haplogroup L4a subclades is based on the paper by Mannis van Oven and Manfred Kayser Updated comprehensive phylogenetic tree of global human mitochondrial DNA variation
and subsequent published research.
    • L4
      • L4a
        • L4a1
          • L4a1a
        • L4a2
