| male meiosis and gametogenesis in wild house mice (mus musculus domesticus) from a chromosomal hybrid zone; a comparison between "simple" robertsonian heterozygotes and homozygotes. | wild male house mice mus musculus domesticus were collected from the hybrid zone between the john o'groats race (2n = 32) and the standard race (2n = 40) in northern scotland. meiosis in both homozygotes (2n = 32, 36, and 40) and single robertsonian heterozygotes (2n = 33, 35, and 37) was found to be orderly. at prophase/metaphase i in heterozygotes, a trivalent was formed from the metacentric and two homologous acrocentrics. at pachytene, this trivalent usually had a single side arm at the posi ... | 1992 | 1424812 |
| a hybrid zone comprising staggered chromosomal clines in the house mouse (mus musculus domesticus). | in the vicinity of john o'groats (caithness, scotland) there is a small karyotypic race of the house mouse (mus musculus domesticus) characterized by a diploid number of 32 chromosomes, including the metacentrics 4.10, 9.12, 6.13 and 11.14. this race forms a hybrid zone with the standard british race (fully acrocentric chromosomes, 2n = 40). although hybrid zones normally consist of several (or many) narrow character clines at the same position, this zone is unusual in that the chromosomal cline ... | 1991 | 1684667 |
| of mice and (viking?) men: phylogeography of british and irish house mice. | the west european subspecies of house mouse (mus musculus domesticus) has gained much of its current widespread distribution through commensalism with humans. this means that the phylogeography of m. m. domesticus should reflect patterns of human movements. we studied restriction fragment length polymorphism (rflp) and dna sequence variations in mouse mitochondrial (mt) dna throughout the british isles (328 mice from 105 localities, including previously published data). there is a major mtdna li ... | 2009 | 18826939 |
