Journal ArticleDOI
B-chromosome evolution.
TL;DR: Because B chromosomes interact with the standard chromosomes, they can play an important role in genome evolution and may be useful for studying molecular evolutionary processes.
Journal ArticleDOI
Chromosome banding in Amphibia. XXVIII. Homomorphic XY sex chromosomes and a derived Y-autosome translocation in Eleutherodactylus riveroi (Anura, Leptodactylidae).
TL;DR: Extensive cytogenetic analyses on a population of the leptodactylid frog Eleutherodactylus riveroi in northern Venezuela revealed the existence of multiple XXAA♂/XYAA♀/XAAY as discussed by the authors.
Book ChapterDOI
CHAPTER 4 – B Chromosomes
TL;DR: In this paper, it was shown that supernumerary chromosomes are common features in many eukaryotic genomes, making a resolution of these issues an integral aspect of genome biology.
Journal ArticleDOI
Possible origin of a B chromosome deduced from its DNA composition using double FISH technique
María Dolores López-León,N. Neves,N. Neves,Trude Schwarzacher,J. S. Heslop-Harrison,G. M. Hewitt,Juan Pedro M. Camacho +6 more
TL;DR: The double FISH technique showed that the B chromosome (B2 type) is mainly composed of a 180 bp tandem repeat and ribosomal DNA, the minute short arm being the only region that does not hybridize with them.
Journal ArticleDOI
A sex-chromosome hybrid zone in the grasshopper Podisma pedestris (Orthoptera : Acrididae)
TL;DR: A comparison of the properties of similar cases indicates that the formation of such chromosomal races may be a frequent event in relatively immobile species that are subjected to isolation and expansion by major climatic and ecological changes.
