Balanced Chromosome Rearrangements
2006Abstract Balanced chromosome rearrangements are those in which there is no overall loss or gain of chromosome material. Unlike single-gene disorders, for which precise calculation of risks to offspring is usually possible, the segregation of chromosome rearrangements does not readily conform to any mathematical model that permits exact ...

Chromosome rearrangements in Giardia lamblia
Parasitology Today, 1994Recent studies have shown that the genome of Giardia lamblia is plastic. Clinical isolates exhibit extensive karyotypic heterogeneity and chromosome rearrangements occur frequently, in vitro. In this review, Sylvie Le Blancq looks at genome organization and the impact of DNA rearrangement events.

Complex chromosomal rearrangements.
Genetic counseling (Geneva, Switzerland), 2007Complex Chromosomal Rearrangements (CCRs) are constitutional structural rearrangements involving three or more chromosomes or having more than two breakpoints. CCRs preferentially occur during spermatogenesis and are transmitted in families through oogenesis.

Rearrangements of Chromosome Segments
1998• Inversions rearrange segments within or between arms of single chromosomes, whereas reciprocal translocations exchange segments between chromosomes. • Inversions and translocations can be detected by changes in mitotic chromosome structure and by distinctive meiotic configurations.

Chromosomal rearrangements and speciation
Trends in Microbiology, 2000Reproductive isolation in the Saccharomyces genus is the result of post-zygotic barriers, as many species mate successfully but the hybrids are sterile. To test whether chromosomal rearrangements were the cause of reproductive isolation (and therefore speciation) in yeast, Fischer et al.1xChromosomal evolution in Saccharomyces. Fischer, G.

Chromosome rearrangements in oncogenesis.
Microbiological sciences, 1990Chromosomal studies have earlier provided evidence for the clonal nature of most neoplasms, and for the role of sequential genetic change in tumour progression. Now, in combination with molecular techniques, they are indicating how the function of specific genes (oncogenes) can be significantly altered by chromosomal translocations or by gene ...
