“…5). This is corroborated by recent biochemical and molecular studies on the Rb system of Peloponnisos, which indicate that in overall, no significant genetic differentiation exists among its populations, including the two Rb races with monobrachial homology (Tryfonopoulos et al 2005).…”

The evolution of the Robertsonian (Rb) system of the house mouse (Mus musculus domesticus) located in Peloponnisos (Greece) is examined, under the possibility of whole arm reciprocal translocation (WART) involvement in the formation process of two of its Rb races with 2n = 24 and 2n = 28, respectively, characterized by monobrachial homology. Our contribution reinforces the opinion that WARTs may have been more actively involved in the formation of Rb races in this subspecies than previously thought. Moreover, the consideration of WARTs, when studying complex Rb systems permits the suggestion of more sensible and parsimonial pathways for their phylogenetic history than when WARTs are excluded.

Although the standard karyotype of the western house mouse, Mus musculus domesticus , consists entirely of acrocentric chromosomes, there are 97 distinct 'populations' that are characterized by various combinations of metacentric chromosomes that have arisen by Robertsonian (Rb) fusions and whole-arm reciprocal translocations (WARTs). In this review we discuss the processes behind the origin and fixation of these rearrangements and then present a unified list of all known metacentric populations and evaluate their phylogenetic relationships. Eleven independent phylogeographical 'systems', each consisting of 2-25 metacentric populations, were identified in Scotland, Denmark, Northern Europe-Northern Switzerland, Southern Switzerland, Northern Italy, Croatia, Spain, Central-Southern Italy, Peloponnesus, Mainland Greece and Madeira. There are six isolated metacentric populations that do not belong to any of these systems. To generate phylogenies of the metacentric populations within each system, we determined those outcomes with the fewest steps regarding accumulation of metacentrics by Rb fusions, WARTs and zonal raciation and taking into account geographical proximity. These phylogenies should be viewed as working hypotheses that will be refined with further chromosomal and molecular data and improvements in methods of phylogenetic reconstruction. The list of metacentric populations and our phylogenies are also published electronically and can be accessed at http://www.studenec.ivb.cz/Projects/RobertsonianMice/.

Molecular insights into the colonization and chromosomal diversification of Madeiran house mice

et al. 2009

The colonization history of Madeiran house mice was investigated by analysing the complete mitochondrial (mt) D-loop sequences of 156 mice from the island of Madeira and mainland Portugal, extending on previous studies. The numbers of mtDNA haplotypes from Madeira and mainland Portugal were substantially increased (17 and 14 new haplotypes respectively), and phylogenetic analysis confirmed the previously reported link between the Madeiran archipelago and northern Europe. Sequence analysis revealed the presence of four mtDNA lineages in mainland Portugal, of which one was particularly common and widespread (termed the 'Portugal Main Clade'). There was no support for population bottlenecks during the formation of the six Robertsonian chromosome races on the island of Madeira, and D-loop sequence variation was not found to be structured according to karyotype. The colonization time of the Madeiran archipelago by Mus musculus domesticus was approached using two molecular dating methods (mismatch distribution and Bayesian skyline plot). Time estimates based on D-loop sequence variation at mainland sites (including previously published data from France and Turkey) were evaluated in the context of the zooarchaeological record of M. m. domesticus. A range of values for mutation rate (mu) and number of mouse generations per year was considered in these analyses because of the uncertainty surrounding these two parameters. The colonization of Portugal and Madeira by house mice is discussed in the context of the best-supported parameter values. In keeping with recent studies, our results suggest that mutation rate estimates based on interspecific divergence lead to gross overestimates concerning the timing of recent within-species events.
