In investigating the dermatoglyphics of hyperactive subjects, it was proposed that if similar hyperactives were sampled and significant differences were found from suitable controls, a genetic effect could be responsible. From two clinical populations, we ascertained 26 subjects in 24 sibships comprising the hyperactive study group. The control subjects(More)
From measurement of the distances between the medial canthi, lateral canthi, and the pupils of 580 black boys and 639 black girls, we present values for these dimensions for 5- to 11-year-old normal subjects. With use of the cranial circumference, we also give normal values for two clinically used indices, the canthal and the circumference-interorbital.(More)
Ring chromosomes have now been observed in all except one group of the human karyotype, though, as yet, a syndrome has not been recognized which is characterized by the presence of a ring. Ring chromosomes have been observed in group A (Gordon and Cooke, 1964), in group B (Rohde and Tompkins, 1965), in group C (Lindsten and Tillinger, 1962; Turner et al.,(More)
The Q-band polymorphism of chromosome 21 permits assignment of the origin of meiotic nondisjunction by parent and meiotic division in a certain proportion of cases. We have compiled all reports through 1982 (including earlier studies using structural abnormality) and have shown that maternal origin accounts for 80% and paternal origin for 20% of trisomic(More)
