Abstract
During International Biological Program studies in Papua, New Guinea, on Karkar Island and at Lufa in the Eastern Highlands [New Guinea], information on anthropometric, biochemical and genetic characteristics was collected from the same individuals. Use was made of this special situation to investigate whether any associations exist between genetic markers and anthropometric and biochemical variation. Those found, and which satisfy criteria established to help in distinguishing real from chance associations, include: P [blood group] with Hb concentration, serum albumin and cholesterol levels; acid phosphatase with serum albumin level and Hb concentration; anhaptoglobinemia and serum globulin level and Hb J-Tongariki with serum P level. The associations are discussed in terms of their arising from the direct result of environmental factors modifying gene expression, chance concordance of environmental and genetic variation, or pleiotropy.
