Economic impact on tooth emergence
As shown in nearly 10,000 Negro and White boys and girls between 4.5 and 16.5 years of age, poverty‐level children (with an income‐to‐needs ratio of 1.0) tend to be delayed in permanent tooth emergence as compared with those approximating median per‐capita income. For boys, a per‐capita income difference of $2200 was associated with a 0.15 standard deviation difference in emergence timiing of 28 permanent teeth
Developmental implications of dichotomous ossification sequences in the wrist region
As shown in radiographs of 3,764 children of European ancestry under 11 years of age, there are 55 dichotomous (present‐absent/absent‐present) ossification sequences for nine wrist region centers in boys and 48 such sequences for girls, with statistically significant sexual dimorphism in more than half of the “alternative” sequences. Substantial samples of Meso‐American origin (“Chicanos”) and largely‐African origin (“Blacks”) evidence additional…
Differential sexual dimorphism in bone diameters of subjects of European and African ancestry
The 1,589 low‐income adult subjects of primarily African ancestry (American Negroes or “Blacks”) showed systematically less sexual dimorphism in total subperiosteal area (TA), medullary area (MA) and cortical area (CA) than did 4,379 low‐income adult subjects of European derivation (“Whites”). These systematic findings have implications both to the sexing of skeletal remains from diverse populations and to an understanding of population divergenc…
Independence of brachymesophalangia‐5 from brachymesophalangia‐5 with cone mid‐5
Analysis of hand radiographs of juvenile siblings of juvenile propositi indicates that brachymesophalangia‐5 alone (without cones) is separately inherited without apparent sex bias while brachymesophalangia‐5 with the cone‐epiphysis of mid‐5 and the cone‐epiphysis of mid‐5 alone are both apparently inherited as a complex and with a marked excess of females over males
Brachymesophalangia‐5 without cone‐epiphysis mid‐5 in Down's syndrome
Brachymesophalangia‐5 proved to be far more frequent in 212 cases of Down's syndrome karyotype (i.e., 21%) than in 14,197 survey volunteers of European ancestry (1.4%). However, none of 28 juvenile Down's syndrome patients with brachymesophalangia‐5 exhibited a cone‐epiphysis on mid‐5, as against the 47% that would be expected. Apparently the manifestation of brachymesophalangia‐5 in the 47,G + karyotype is not simply a dosage effect associated w…
Size reduction associated with brachymesophalangia‐5: A possible selective advantage
Subjects with brachymesophalangia‐5 (the short middle segment trait of the fifth digit) are systematically reduced in the length of the second metacarpal and in stature, by approximately 0.5 standard deviations, in contrast with unaffected individuals or unaffected siblings of affected propositi. There is conclusive evidence for axial and appendicular length reduction in affected individuals, and the smaller body size associated with brachymesoph…
The operational meaning of maturity criteria
The fact that specific radiographic criteria represent different proportions of attained maturity in males and females, in individuals of different geographical origin, in undernourished as opposed to over‐nourished subjects and in genetic or chromosomal extremes together indicates the operational complexity of “skeletal maturity” and indicates the need to separate those aspects of skeletal development that are not sex‐hormone dependent from thos…
