Groupes sanguins des Ammassalimiut en 1935

Abstract : Ammassalimiut blood groups in 1935. We determined in 1934-35 the ABO blood-groups among Ammassalik eskimo of the east coast of Greenland. They are the first blood groups taken at Ammassalik. At this time this eskimo population of 908 people had lately come out of Prehistory ; 413 people discovered in 1884, so it already knew a great demographic expansion. Our sample is exclusive of any cross-breeding. All our determinations had been nominative: each person is written down in a genealogy tracing back to several generations. So the results of this blood groups of 1935 constitute basic references for all the later studies and interpretations ; they can be analysed taking in account lineages and cohorts. Out of this eskimo population of 908 inhabitants (on the 31-12-35) we determined ABO blood groups of 611 persons, that is to say 67,2 % of the total number of inhabitants and 76,6 % of the population over 10 years. The phenotypes and genes frequencies are given above. V. Fabricius Hansen to whom we had communicated our results, as soon as 1936, took in Ammassalik, three years later, the blood of 580 subjects and published the results for 569; most of them had already been examined by us. This author, recently told us that she has not any longer the nominative list of her subjects; so it is impossible to know whether V. Fabricius Hansen has determined some subjects non-examined by us, which would have increase the number of references of which we dispose for this period. It is really unfortunate that the 569 subjects published by V. Fabricius Hansen in 1939 cannot be used by population genetics, their names and genealogy being unknow. Regarding the anthropological interpretation of these blood groups, the two series (R. Gessain 1935, 611 subjects and V. Fabricius Hansen 1939, 569 subjects) concern the same population and in a very large extent (unfortunately impossible to precise) the same persons.Gessain Robert.
