title: Further note on possible changes in the geographic distribution of ABO and RH blood groups in Great Britain.
abstract: We previously reported the tendency for the clines of blood group distributions in England, Scotland, and Wales to become flatter as the result of internal migration. The data came from a one-week birth cohort followed for 16 years. A further seven years and a finer geographic analysis yield mixed results. The Rh- clines did become flatter, but the clines for ABO blood groups A and O showed the opposite tendency during the additional years.
