Summary and Conclusions
Aspects of the distribution of HbS in the United States
Frequencies of HbS obtained by several screening clinics are analyzed for age, sex, and location effects. All seem to be present in some form, though age and sex effects may be conditional on location. An attempt is made to elaborate the common observation of increasing frequency with age. This is shown to be the result of differences in fertility favoring the normal. A simulation which íncludes 25% admixture was done. The results indicate a gene…
A note on the estimation of allele frequencies
A new method of obtaining allele frequency estimates is described. The method may prove useful when maximum likelihood estimates are not available. No assumptions regarding the absence of alleles are required. Errors of estimates have not been obtained, but the process seems to converge to maximum likelihood
Blood groups of six Indian bands of north‐eastern British Columbia
A survey of nine blood group systems was conducted among some northeastern British Columbia Indian bands. The sites contain Beaver, Slave and Cree speakers. A significant departure from Hardy‐Weinberg equilibrium was observed in the combined MNS system. No age trends by sex were observed
Blood groups and red cell enzymes of the Ross River (Northern Tuchone), and Upper Liard (Slave) Indians
A survey of nine blood group systems was conducted as part of a study of health and nutrition among two Athapsakan groups of the Yukon Territory, Canada. Most of the samples were also analyzed for hemoglobin patterns and G‐6‐PD variants. The only significant difference in allelic frequencies between the two populations occurred at the P locus. An apparent deficit in the observed frequency of type A 1 , and hence a departure from equilibrium, at U…
Blood Pressure Changes among Male Navaho Migrants to an Urban Environment
Des donnees comparatives sur la pression sanguine systolique et diastolique des Navahos de sexe masculin furent recueillies avant et apres leur emigration d'un milieu rural a un centre urbain. Les deux mesures furent significativement plus elevees apres l'emigration. Quelques facteurs causaux tels que le changement d'altitude, l'ingestion de gras satures et l'age furent elimines. D'un maniere pro‐visoire, on conclut que des facteurs associes a l'…
Blood groups, phosphoglucomutase, and cerumen types of the Anaham (Chilcotin) Indians
A survey of the blood groups of a Chilcotion band produced unexpected results for the ABO system (0.69 for allele 0, 0.31 for allele A), MNSs system (0.53 for antigen M, 0.47 for antigen N), P (0.36 for P 1 ). Other loci surveyed were within the range of expectation. The frequency of phosphoglucomutase type PGM was found to be 0.87, and for the dry cerumen allele 0.57. The frequency of the A allele was found to be decreasing among males, and seve…
Blood groups, red cell enzymes, and cerumen types of the Ahousat (Nootka) Indians
A survey of the blood groups of a Nootka band produced frequencies characteristic of North American Indians for the ABO system (0.99 for 0, 0.0 for B, and 0.01 for A), Rhesus (0.822 for cDE, 0.011 for cde, 0.023 for cDe), Lutheran (1.00 for Lu(a—)), Duffy (0.505 for Fy(a+)) and Diego (0.039 for Di(a+)). K is not absent though the frequency is not great (0.028). Surprising results were obtained for the MN locus (0.399 for M, 0.601 for N), P (0.209…
