Distribution of ABO Blood Groups on the Indian Subcontinent: A Cluster-Analytic Approach [and Comments and Reply]
This paper attempts a comprehensive statistical analysis of the O-A-B-AB blood-group frequencies collected from the Indian subcontinent. The objective is to examine the variation in ABO gene frequencies among populations using statistical tests of homogeneity and single-linkage cluster analysis. In all, 899 sets of phenotype frequency data were examined. Of these, 405, each based on a sample of at least 100 individuals and in conformity with Hard…
The Evolutionary Relationships of Two Populations: A Study of the Guaymi and the Yanomama [and Comments and Reply]
A multidisciplinary study of the Guaymi of western Panama was undertaken to confirm or disprove their apparent similarity to the Yanomama of southern Venezuela and northern Brazil, inferred from allele frequencies for six polymorphic loci studied in the Guaymi by Matson and colleagues in 1965. Gene frequencies were estimated from the present sample of 484, which is more than twice as large as the previous sample and appears to be completely indep…
On Natural Selection and the Inheritance of Wealth [and Comments and Reply]
Greater reproductive variance among males than among females is presented as a component of natural selection's influence in determining preferential treatment of males in the inheritance of wealth. In conjunction, the transmission of sex chromosomes and their attendant probabilities of carrying genes identical by descent are traced for several generations in order to illustrate a male bias in species whose male sex is heterogametic (XY) while th…

Genetic studies in Paraguay: Blood group, red cell, and serum genetic patterns of the Guayaki and Ayore Indians, Mennonite settlers, and seven other Indian tribes of the Paraguayan chaco
Genetic studies of 540 Paraguayan Indians from nine tribal groups and 51 Mennonites are presented for ABO, MNSs, P 1 , Rh, Kell, Lewis, Duffy, Diego; for serum immunoglobulins and haptoglobins, G6PD‐deficiency, and thalassemia trait. Group O gene frequencies for all Indian groups were 1.00; for r (cde) , 0.00. Tapiete, Lengua, Toba, and Sanapana R z ( CDE ) frequencies were among the highest ever reported. N frequencies were high for Ache Kwera (…
The ethnological significance of the gamma‐globulin (Gm) factors in Melanesia
A study was made of the distribution of the immunoglobulin markers Gm(a), (x), (z), (f), (g), (b 0 ), (b 1 ), (b 3 ), (s), (t), (c 3 ), (c 5 ) and Inv (1) and Inv (a) in 906 individuals sampled from several population groups living in various parts of New Guinea and New Britain. A study of 123 families confirmed the presence of the following gene complexes: Gm za;g , Gm zax;g , Gm za;b and Gm fa;b . Gm(s), (t), (c 3 ) and (c 5 ) were absent and e…
The distribution of haptoglobin and transferrin types in northeast New Guinea
This paper reports haptoglobin testing of 2,029 serum specimens and transferrin typing of 1,911 specimens obtained from villages representing a wide range of environments and cultures in the Markham River Valley region of northeast New Guinea. The haptoglobin gene frequencies ranged from 90.0% to 61.4% for Hp 1 and the frequency of the transferring gene Tf c ranged from 94.9% to 71.5%. Other transferrin genes present were Tf D1 and, in low freque…
Distribution of β‐thalassemia trait and erythrocyte glucose‐6‐phosphate dehydrogenase deficiency in the Markham river valley of New Guinea
Ten villages in or near the Markham Valley, northeastern New Guinea, have provided a sample of 476 males for the ascertainment of glucose‐6‐phosphate dehydrogenase (G6PD) deficiency and 810 individuals of both sexes for the investigation of the β‐thalassemia trait. An extreme heterogeneity was found in the prevalence of both traits when the villages were analyzed separately (from 1.5% to 18.2% demonstrating G6PD deficiency and from 0 to 22.8% evi…
Distribution of the group specific (Gc) serum component in the populations of the Markham Valley, New Guinea
The distribution of the Gc phenotypes was determined by immunoelectrophoresis amongst 486 inhabitants of nine villages of the Markham River Valley of New Guinea. The overall gene frequencies were Gc 1 , 0.538; Gc 2 , 0.351; Gc Aborigine , 0.112. Gc Aborigine occurred in all the villages, its frequency ranging from 0.041 to 0.187. The Gc 2 gene frequency also varied widely ranging from 0.167 to 0.491. No correlation could be found between altitude…
Haptoglobins and transferrins in Melanesia: Relation to hemoglobin, serum haptoglobin and serum iron levels in population groups in Papua—New Guinea
This paper reports haptoglobin and transferrin typping of 2687 serum specimens from Melanesians of New Guinea and New Britain. The specimens were obtained from members of 27 different cultural and linguistic groups residing in over 100 different villages in six different administrative districts. They were divided among the Districts as follows: New Britain 821, Sepik 623, Morobe 349, Eastern Highlands 613, Southern Highlands 222, and Western Hig…
