Study topics may include developments in the mitochondrial DNA (mtDNA) haplogroup tree and origins of haplogroups, histories of particular groups of people, research into medical conditions, and others. Many studies will combine multiple topics. For example, a study focusing on a particular population group may also expand the haplogroup tree adding to our understanding of some of its branches.
