Chromosomal Mapping of Repetitive DNAs in the Grasshopper Abracris flavolineata Reveal Possible Ancestry of the B Chromosome and H3 Histone Spreading
(2013-06-27)
Supernumerary chromosomes (B chromosomes) occur in approximately 15% of eukaryote species. Although these chromosomes have been extensively studied, knowledge concerning their specific molecular composition is lacking in ...

Structural and functional evidence that a B chromosome in the characid fish Astyanax scabripinnis is an isochromosome
(Blackwell Science, 2000-07-01)
Astyanax scabripinnis possesses a widespread polymorphism for metacentric B chromosomes as large as the largest chromosome pair in the A complement. on the basis of C-banding pattern, it was hypothesized that these B ...
Y chromosome sequences in Turner's syndrome: Association with virilization and gonadoblastoma
(FREUND PUBLISHING HOUSE LTD, 2003)
The presence of Y chromosome fragments in patients with Turner's syndrome is known to increase the risk of gonadoblastoma and virilization. Y chromosome material is detected in up to 6% of patients with Turner's syndrome ...
Genomic content and new insights on the origin of the B chromosome of the cichlid fish Astatotilapia latifasciata
(Springer, 2011-10-01)
B chromosomes are additional chromosomes widely studied in a diversity of eukaryotic groups, including fungi, plants and animals, but their origin, evolution and possible functions are not clearly understood. To further ...
