House Mice as Models in Systematic Biology
The house mouse and its laboratory descendents are evaluated as models for three aspects of systematic biology: hybrid zone biology, chromosomal evolution and speciation, and tests for methods of phylogenetic reconstruction. Expand

Pericentromeric organization at the fusion point of mouse Robertsonian translocation chromosomes.
Rb translocation breakpoints were found localized within the minor satDNA of telocentrics, and these sequences contributed symmetrically to the formation of the centromeric region of the Rb chromosomes. Expand
Robertsonian metacentrics of the house mouse lose telomeric sequences but retain some minor satellite DNA in the pericentromeric area
The absence of telomeric sequences and the reduced amount of minor satellite sequences at the pericentromeric region of the R b metacentrics suggest that the breakpoints for the Rb translocation occur very close to the minor satellite-major satellite border. Expand
Molecular systematics and evolutionary biogeography of the genus Talpa (Soricomorpha: Talpidae).
The molecular systematics of the genus Talpa are assessed using the mitochondrial gene cytochrome b from eight of the nine extant species of Talpa moles to suggest a monophyletic origin and a common ancestor for the western European moles, suggesting a Miocene origin of the extant moles. Expand
The other chromatin
The functions and effects of heterochromatin on differential DNA endoreplication and in speciation are discussed, and the contributions of Sigrid and Wolfgang Beermann are recalled. Expand
Contact zone between chromosomal races of Mus musculus domesticus. 2. Fertility and segregation in laboratory-reared and wild mice heterozygous for multiple Robertsonian rearrangements
Litter size, anaphase I nondisjunction and X–Y dissociation at metaphase I were studied in homozygous and heterozygous house mice from a central Italian chromosomal hybrid zone and the stability of this hybrid zone through time is discussed. Expand
The Chromosomes of Some Mediterranean Teleosts: Scorpaenidae, Serranidae, Labridae, Blenniidae, Gobiidae (Pisces — Scorpaeniformes, Perciformes)
Viene riferito il numero diploide e la morfologia del cariotipo di 11 specie di Teleostei mediterranei e la interpretazione di coppie cromosomiche eteromorfe messe in evidenza in Labridi e Gobidi. Expand
Chiasma Repatterning Across a Chromosomal Hybrid Zone Between Chromosomal Races of Mus Musculus Domesticus
The progressive reduction of chiasmata indicates that genes could pass from one race to another in an asymmetrical way: from metacentric races to the standard population. Expand
Molecular phylogenetics of the genus Gerbillus (Rodentia, Gerbillinae): Implications for systematics, taxonomy and chromosomal evolution.
Findings based on the whole cytochrome b (1140 bp) mitochondrial genes of seven species of gerbils show that all the Gerbillus species are monophyletic, and molecular phylogeny rejects the genus rank for the taxon Dipodillus. Expand
