摘要:

SummaryOut of 292 boys and 272 girls tested for colour blindness in Andhra Pradesh 22 boys and one girl were judged to have abnormal colour vision. Difficulties in classification are emphasized.We are grateful to Dr H. Kalmus for his advice on the classification of abnormals and to Dr H. Spurway for criticizing the manuscript.

摘要:

SummaryA 7‐month‐old pair of mongoloid twins is described (one of which died) who both had 48 chromosomes withA A + A21XXY.The pair must have been an identical twin, who would develop Klinefelter's syndrome.L. E. Nijenhuis (Anthropogenetics Dept. Red Cross Blood Transfusion Laboratory, Amsterdam) informed us on the data of blood groups. We are indebted to E. D. A. M. Schretlen, paediatrician (Paediatric Clinics, R.C. University) for performing tibia puncture. Our thanks are due to W. G. van Aken (med. student), Miss M. A. W. Janssen and A. P. Jansen for valuable assistance in counting, analysing and technical help. Dr J. C. Seelen, M.D. (Gynaecological Clinics, R.C. University) gave valuable help in evaluating the preparations for Barr‐b

摘要:

SummaryThe application of a factorial analysis of x2to sex ratio data is discussed. It is shown how such an analysis resolves the main sources of variation in binomial data. Some extensive data are treated by this method, and it is concluded that they provide good evidence for a positive association between the sexes of successive children in a family.

摘要:

Summary1. The total frequency of colour blindness among 245 Caingang Indians and Mestizos males is 4–49 %. But there exists variation of this frequency in the populations sampled.2. Several pedigrees are given of kindreds in which some members present Polydactyly or albinism. The high frequency of this last condition in one population is stressed.3. A general discussion of the data (which appeared in all articles of this series) is included. Examples of the possible influence of gene flow, genetic drift and natural selection in determining the frequencies of some genes are given.4. The four populations studied can be grouped into two main evolutive complexes.This work has been supported in part by grants from the Rockefeller Foundation and Comissao de Pesquisas of the University of Rio Grande do Sul. The technical assistance of Mr Girley V. Simoes is gratefully acknowledge

摘要:

SummaryManner of hand clasping was investigated in 688 Spaniards. The analysis of the series of unrelated individuals suggests a sexual bimodality in the trait, the female series containing higher R frequency than the male. The frequency of R individuals in both sexes increases with age. The analysis of family data shows some parental influence on the type of hand clasping, but no simple Mendelian mechanism is found. There is no assortative mating.

摘要:

SummaryIn a survey of mentally retarded males with small testes, a man was found whose sex chromosome complement has been interpreted asXXYY.The family history gave no indication as to the origin of the anomaly and various possibilities are discussed. Non‐disjunction of theY‐chromosomes at the second meiotic division in spermatogenesis combined with some other accident producing two X‐chromosomes in sperm or ovum is postulated. Clinical and pathological investigation revealed a number of physical peculiarities, including absence of most of the left epididymis associated with testicular atrophy. His stature is 6 ft. 5 in.The writers are indebted to many people who have helped them at different points in this investigation. They would like to take this opportunity of thanking Dr D. H. H. Thomas for granting facilities, Mr D. S. Morgan‐Jones for obtaining biopsy material, Drs J. Munro Sherriff and I. F. Sommerville for ketosteroid and other endocrine estimations, Miss M. Mann for preparing histological sections, Dr Sarah B. Holt for examining the finger ridge patterns, Miss B. J. Warland for obtaining the family history and Mr C. Payling Wright and Mr N. Bishun for technical ass

摘要:

SummaryAn unusual chromosomal constitution,XXxY/XXY, with both mosaicism and a probable partial deletion of an ‐X‐chromosome is reported in a case of Klinefelter's syndrome associated with severe thalassaemia. Evidence is submitted for regarding the association as coincidental.The literature regarding chromosomal constitution in Klinefelter's syndrome is reviewed and the possible mechanisms by which the constitution might have arisen in this patient are discussed.This work was carried out whilst holding a grant from the British Empire Cancer Campaign.I am grateful to Dr E. R. Huehns for some of the haematological investigations and for helpful discussion and to Mrs Joy Delhanty for assistance with the skin culture.I would also like to thank Prof. L. S. Penrose and Dr T. A. J. Prankerd for reading the manuscript and the latter for permission to study this c
