aClades were defined according to the definitions in spolDB3.0 (6); = no hybridization, = positive hybridization. CAS1 (Central Asian 1) family (also termed as the "Delhi type") is characterized by 4–7 and 23–34; Manu (derived from the name of a Hindu mythological figure supposed to be the world's first king and father of the human race) is characterized by 33–34 (5), and presumed to be the probable ancestor of both the CAS and EAI (East African Indian). Beijing family is characterized by 1–34. Both EAI and CAS1 belong to the Major Genetic Group 1; H3 (Haarlem 3) belongs to the Major Genetic Group 2; and T1 and T2 are poorly defined families that belong to the Major Genetic Group 2 or 3 (11). T1 and T2 need other markers for a better characterization (T1, 33–36 and T2, 33–36 and 40 ).
