▁The ▁frequencies ▁of ▁H ap lo group ▁O - M 1 1 9 ▁among ▁various ▁East ▁Asian ▁and ▁Aust ron esian ▁populations ▁suggest ▁a ▁complex ▁gen etic ▁history ▁of ▁the ▁modern ▁Han ▁populations ▁of ▁southern ▁China . ▁Although ▁H ap lo group ▁O - M 1 1 9 ▁occurs ▁only ▁at ▁an ▁average ▁frequency ▁of ▁approximately ▁ 4 % ▁among ▁Han ▁populations ▁of ▁northern ▁China ▁and ▁pe op les ▁of ▁south western ▁China ▁and ▁S out heast ▁Asia ▁who ▁speak ▁Tib eto - B ur man ▁languages , ▁the ▁frequency ▁of ▁this ▁ha p lo group ▁among ▁the ▁Han ▁populations ▁of ▁southern ▁China ▁nearly ▁quad ru ples ▁to ▁about ▁ 1 5 - 2 3 %. ▁The ▁frequency ▁of ▁H ap lo group ▁O - M 1 1 9 ▁among ▁the ▁Southern ▁Han ▁has ▁been ▁found ▁to ▁be ▁slightly ▁greater ▁than ▁the ▁arithmetic ▁mean ▁of ▁the ▁frequencies ▁of ▁H ap lo group ▁O - M 1 1 9 ▁among ▁the ▁Northern ▁Han ▁and ▁a ▁po o led ▁sample ▁of ▁Aust ron esian ▁populations . ▁This ▁suggests ▁that ▁modern ▁Southern ▁Han ▁populations ▁may ▁possess ▁a ▁non - t rivial ▁number ▁of ▁male ▁ancest ors ▁who ▁were ▁originally ▁affili ated ▁with ▁some ▁Aust ron esian - related ▁culture , ▁or ▁who ▁at ▁least ▁shared ▁some ▁gen etic ▁aff inity ▁with ▁many ▁of ▁the ▁ancest ors ▁of ▁modern ▁Aust ron esian ▁pe op les . ▁ ▁Sub cla de ▁distribution ▁ ▁O - M 1 1 9 ▁This ▁line age ▁is ▁found ▁frequently ▁in ▁Aust ron
