“…Blood group determinations were done according to the methods recommended by Race and Sanger (1975). Hemoglobins, serum protein, and red cell enzyme types were determined using methods according to Blake and Omoto (1975) and Mazzur and Blake (1981). The number of individuals typed differs very slightly from system to system due to the limited availability of certain antisera and the deterioration of a few specimens in transit.…”

Allele frequencies are reported for 19 blood group, red cell enzyme, and serum protein loci (ABO, Rh, MN, Hb-A, LDH-A, LDH-B, SOD, PGM-1, PGM-2, 6PGD, GPT, ESD, ADA, ACP, PGK, MDH, Alb, Hp, and Tf) determined from 310 blood samples collected among the Gainj, a small population of tribal horticulturalists from highland Papua New Guniea. Fourteen of these loci display genetic variants, and ten of them are sufficiently polymorphic to permit a preliminary analysis of Gainj population structure. Patterns of variation among subdivisions of the population are analyzed using an approach analogous to a multivariate analysis of variance with unbalanced design, and weighted genetic distances are extracted from the results. The distance analysis indicates that patterns of genetic variation within this population reflect the geographical distribution of subdivisions, as well as subdivision size and movement among subdivisions. A parallel analysis of the Gainj and two other tribal groups from highland New Guinea, the Murapin Enga and the Simbai Valley Maring, suggests that the Gainj are both genetically divergent from neighboring populations and internally highly differentiated.

“…For most of the samples, ABO typing was carried out by reverse grouping using the presence or absence of anti-A or anti-B antibodies in the separated aliquots of serum. Serum protein and red cell enzyme typing was carried out using the methods outlined by Mazzur and Blake (1981). RESULTS Blood specimens were examined from a total of 2,368 individuals from the populations listed in Table 1.…”

A population genetic study of the Banks and Torres Islands (Vanuatu) and of the Santa Cruz Islands and polynesian outliers (Solomon Islands)

As part of a multidisciplinary survey of populations in the Banks and Torres Islands of Vanuatu and the Southern and Central Districts of the Solomon Islands, nearly 2,400 persons have been tested for ABO blood groups and a number of serum protein and red cell enzyme genetic marker systems. For the ABO system, the populations are characterized in general by high gene O and low gene B frequencies except in two of the Polynesian Outlier Islands, Rennell and Bellona, which have high frequencies of B. Among the serum proteins, several alleles have distributions indicating significant movement of people between islands. These include Albumin New Guinea and the transferrin alleles TfD1, and TfBLae, and TfB2. Similar specific alleles for red cell enzymes also show distributions reflecting interisland population movement as well as contact with persons from outside the southern Pacific region. Examples are ACPR1 in the acid phosphatase system, PGM31 and PGM71, PGM92, and PGM102, PGK4 and also HbJTongariki. The data available for 11 polymorphic systems were used to generate genetic distances. Of the four Polynesian Outlier Islands, Anuta is most remote genetically, with Rennell and Bellona also relatively isolated. The fourth Polynesian Outlier, Tikopia, occupies a position genetically close to the Melanesian populations of the Banks and Torres Islands and the southern Solomons. The history of early European contact and voyaging in the Pacific, as well as archaeological and linguistic evidence and local legends, indicate that significant movements of people occurred between islands and provided opportunities for genes to be introduced from Europeans, Africans, and Asians. The genetic marker studies give evidence for genes from all these sources, though at a low level. Despite this admixture, the Polynesian Outlier and Melanesian populations have preserved their own distinctive genetic patterns.

Genetic Variants of 6-Phosphogluconate Dehydrogenase in the Indonesian Populations

Blood samples from 2,091 individuals representing 14 Indonesian populations (11 Austronesian and 3 non-Austronesian speakers) have been tested electrophoretically for 6-phosphogluconate dehydrogenase (6-PGD). Two common alleles, PGD^A and PGD^C are found in all populations studied, and the phenotype distribution agrees well with the Hardy-Weinberg equilibrium. The PGD^C gene frequency varies from as low as 3.5% in the Galelarese to 29% in the Asmat. In general, the PGD^C allele seems to decrease in frequency towards the west. A low frequency of PGD^C in the Galelarese, a non-Austronesian-speaking population, is thought to be the result of admixture of Austronesian genes, which has not led to language change. In addition to the common alleles, a new variant, PGD A-Lombok, is also described.
