DNA replication studies of human D-group chromosomes in satellite associations.
TLDR
DNA replication studies were carried out on metaphase plates showing satellite associations to determine the association of individual D chromosomes.Abstract:
DNA replication studies were carried out on metaphase plates showing satellite associations to determine the association of individual D chromosomes. In a total of 279 D chromosomes involved in satellread more

Ionizing Radiation: Sources and Biological Effects
TL;DR: In this paper, the authors present an Ionizing Radiation Sources and Biological Effects (IRBE) study, in which the sources and biological effects of ionizing radiation are investigated and compared.

Theoretical bases for karyotype evolution. I. The minimum-interaction hypothesis.
TL;DR: The "minimum-interaction hypothesis" states that karyotype evolution has been in large part shaped by selection to reduce the occurrence of such fitness-reducing spontaneous chromosomal mutations as reciprocal translocations.

Ribosomal DNA Connectives between Human Acrocentric Chromosomes
TL;DR: The overall frequency of associations in metaphase varies with techniques of cell culture and preparation as well as with the individual, so individual variation may account for contradictory reports concerning correlation of association characteristics with age, sex, and chromosomal abnormalities.
Quantitative studies on the arrangement of human metaphase chromosomes. II. Influence of the preparation technique on the association pattern of the acrocentric chromosomes.
TL;DR: The spatial relationships between the homologous pairs of chromosomes in the normal human colcemid-treated metaphase plate were tested by two different mathematical approaches.

TL;DR: In this paper, the association pattern was studied in 1182 mitoses of 21 patients with trisomy 13 and in a control group, and 173 trisomic mitoses were compared with the same number of diploid mitoses in a case of mosaicism.
