Since their discovery more than a century ago, they have been a source of puzzlement, as they only occur in some members of a population and are absent from others. When they do occur, they are often harmful, and in the absence of ?selfishness?, based on mechanisms of mitotic and meiotic drive, there appears to be no obvious reason for their existence. Cytogeneticists have long wrestled with questions about the biological existence of these enigmatic elements, including their lack of any adaptive properties, apparent absence of functional genes, their origin, sequence organization, and co-evolution as nuclear parasites. Emerging new technologies are now enabling researchers to step up a gear, to look enthusiastically beyond the previous limits of the horizon, and to uncover the secrets of these ?silent? chromosomes. This book provides a comprehensive guide to theoretical advancements in the field of B chromosome research in both animal and plant systems. 610 $aparent-of-origin effects 610 $afluorescent in situ hybridization 610 $acoverage ratio analysis 610 $aribosomal DNA 610 $areactivation 610 $acytogenetics 610 $aepigenetics 610 $aheterochromatin 610 $ainterphase nucleus 610 $awhole genome resequencing 610 $atransmission 610 $agrasshoppers 610 $agenome instability 610 $adot-like (micro) Bs 610 $a?s 610 $aB chromosome 610 $asupernumerary elements 610 $atranscription of heterochromatin 610 $amaternal X chromosome 610 $asupernumerary chromosome 610 $apopulation analysis 610 $asupernumerary 610 $arepeat clusters 610 $aextra chromosomes 610 $agenes 610 $atandem repeats 610 $aB morphotypes 610 $arepetitive DNA 610 $arepetitive elements 610 $aDNA copy number variation 610 $achromosome polymorphism 610 $asatellite DNA 610 $amammals 610 $amaize B chromosome 610 $aadditional chromosomes 610 $ainactivation 610 $adrive 610 $aB chromosomes 610 $aFISH (fluorescence in situ hybridisation) 610 $aorganelle DNA 610 $aOrthoptera 610 $aorigin 610 $asupernumerary chromosomes 610 $akaryotype evolution 610 $aGISH (genomic in situ hybridisation) 610 $aDNA composition 610 $ade novo centromere formation 610 $agenomics 610 $apaternal X chromosome 610 $aeuchromatin degradation 610 $asupernumerary chromosomal segments (SCS) evolution 610 $acentromere 610 $asSMC 610 $aProspero autumnale complex 610 $anext-generation sequencing 610 $aDrosophila 610 $ahost/parasite interaction 610 $aApodemus peninsulae 610 $agenome evolution 610 $aevolution 610 $ateleost 610 $achromosome evolution 610 $amicrodissected DNA probes 610 $acontrolling element 610 $amobile element 610 $aRNA-Seq 610 $akaryotypes 610 $akaryotypic characteristics 610 $aRepeatExplorer 700 $aMartins$b Cesar$4auth$01315346 702 $aTrifonov$b Vladimir$4auth 702 $aHouben$b Andreas$4auth 702 $aJones$b Neil$4auth 906 $aBOOK 912 $a9910346673503321 996 $aEvolution, Composition and Regulation of Supernumerary B Chromosomes$93032355 997 $aUNINA
