Thirty-five males with double Y chromosome

Psychological Medicine, 1974
SYNOPSISThirty-five males with double Y chromosome were studied. Among the features observed in certain subgroups of these 35 were a more than average height, minor vertebral abnormalities, abnormal seminiferous epithelium, minor EEG abnormalities, and a mean intelligence level significantly below the expected.

Male sterility and double heterozygosity for chromosomal inversion

Cytogenetics and Cell Genetics, 2008
A meiotic analysis has been carried out on male mice heterozygous for one of two inversions in Chromosome 2, In(2)5Rk and In(2)2H, as well as on double heterozygotes for these two overlapping inversions. Electron microscopic observation of synaptonemal complexes revealed that heterosynapsis had occurred in a large number of spermatocytes, producing a ...

Chromosome doubling of haploids of common wheat with caffeine

Genome, 1997
Treatment of dividing plant cells with caffeine inhibits their cytokinesis, thereby inducing the formation of binucleate cells that contain polyploid nuclei. This study was undertaken to determine whether caffeine treatments would induce chromosome doubling and seed set in haploids of common wheat (Triticum aestivum L. em.

Double minute chromosomes in an invasive adenocarcinoma of the prostate

Cancer Genetics and Cytogenetics, 1994
Cytogenetic analysis of an uncultured, primary and invasive adenocarcinoma of the prostate showed several clonal abnormalities in a hyperdiploid karyotype, including double minute (dmin) chromosomes. The latter, although sporadic in this type of tumor, were previously reported in two cases of invasive prostatic cancer.

Double Ph1 chromosomes in chronic granulocytic leukemia

Cancer, 1967
Two cases of chronic granulocytic leukemia were considered atypical because abnormal “monocytoid” granulocytes and morphological abnormalities of the erythrocytes were present. This suspicion was confirmed by the course of the disease and by the existence of several abnormal chromosome cell lines in both patients, including double Ph1 chromosomes.

DNA Double Strand Breaks and Chromosomal Aberrations

Cytogenetic and Genome Research, 2010
DNA double strand breaks (DSBs) are ultimate lesions for the formation of chromosomal aberrations (CAs). The formation of CAs is dependent on many factors; some of these are discussed in this review. FISH methodologies have uncovered CA types which cannot be seen with the classical staining methods, and thereby widened our understanding of the origin ...

The chromosomal aberraation of double-minutes in three gliomas

Acta Neuropathologica, 1970
Thkek chromosomes of about 40 human malignant gliomas in adults have been studied. Three tumours had double-minutes (dms) in all or most of their cells whereas 5 additional gliomas showed the same aberration in sporadic cells. The humber of dms varied between 1 and more than a hundred.

Double-strand breaks on artificial chromosomes in yeast

Chromosoma, 2000
Yeast artificial chromosomes composed primarily of bacteriophage gamma DNA exhibit very low levels of meiotic crossing over compared with similarly sized intervals of natural yeast DNA. When these recombinationally quiet chromosomes were augmented with a 12.5 kb insert of sequences from yeast chromosome VIII, genetic studies demonstrated that the ...

Phenotypic Consequences of Chromosome Doubling

2002
Abstract It is important to uncouple the effects of chromosome doubling from those of hybridization or genome coexistence, because only then can we understand the manifold effects of polyploidy alone (autopolyploid) within individuals, populations, and species.
