pericentric inversions of chromosome 9 are among the most frequent chromosomal rearrangement in human. a few cytogeneticists consider inversions of chromosome 9 as a normal variant. however, many reports in the recent literature link pericentric inversions of chromosome 9 with infertility, recurrent abortions, and a number of other abnormal conditions. we report a case of homozygosity pericentr...

XTENSIVE chromosomal polymorphism, probably due to pericentric inverE sions, has been reported in animals as dissimilar as grasshoppers (WHITE 1958) and mice ( OHNO et al. 1966). Inversion polymorphism is also prevalent in natural populations of many Drosophila species, but rarely are the inversions pericentric. The infrequency with which pericentric as compared with paracentric inversions are ...

Chromosomal inversions appear to be common in many organisms, but their frequency in humans is not known. Routine human mitotic chromosome studies have shown few pericentric inversions, and meiotic studies, which can reveal pericentric and paracentric inversions, have been less extensively applied to human chromosomes. The evaluation of possible chromosomal inversions has also been limited by n...

It is well-accepted that studies of chromosomal changes which have occurred during the evolution of the great apes and the human provide clues towards the phylogeny of these species. Applying recently developed molecular cytogenetic approaches, this study on the chromosomes of the orangutan and the gorilla revealed the presence of cryptic, until now, unrecognized cytogenetic rearrangements main...

Chromosomal rearrangements are common in humans. Pericentric inversions are among the most frequent aberrations (1-2%). Most inversions are balanced and do not cause problems in carriers unless one of the breakpoints disrupts important functional genes, has near submicroscopic copy number variants or hosts "cryptic" complex chromosomal rearrangements. Pericentric inversions can lead to imbalanc...

Wedge shells belonging to the Donacidae family are the dominant bivalves in exposed beaches in almost all areas of the world. Typically, two or more sympatric species of wedge shells differentially occupy intertidal, sublittoral, and offshore coastal waters in any given locality. A molecular cytogenetic analysis of two sympatric and closely related wedge shell species, Donax trunculus and Donax...
