A cytogcnic study of nearly 200 h o u r niicc (.\fits I T I I~. W U~U Jsensu Jtrirto) and aboriginal mice (Afu hor/rtlnnir.s, .2fus abbotti) of the subgrnus , l f i t~ was carried out. Mice were sampled from most localitics in the fornirr U.S.S.R.. from thr western borders to the Far East, and it was shown that i t is possible to usr eytogenrtic markrrs to classify the apecies and rarr subspecies of the suhgenus. Surh markers included the characteristic morphology or the sex chromosomes and the pattrrn of distribution of the C:-heterochromatiri in thr karyotype. Thus. the abori+nal mice, togrther with M . sprdits, arr characterized by a significant reduction in the size of the Y chrornosomr. In addition, the variant of the X chrornosomr (so called 'mulosrinu' type) previously only observed in Japanese ,\I. m. moloJJinu was found in all the A~U J musrulus sampled from thc fauna of the former U.S.S.R. Another type, the so called 'doms/tcuJ', is a plcsiomorphic variant of' the S chromosome which is normally found in .21. domrstim. .\f. h i n t~l n~u~. .\f. nhbofti and possibly in 111. ~pretus.

“…This fact stems from karyograms obtained by Spanish authors comparing M. spretus and M. m. domesticus (Cano et al, 1984) and the drawing given in one relatively old paper (Matthey, 1955) illustrating the spermatogonial metaphase of a male from Oran. The fact of Y-chromosome differences was nevertheless not discussed.…”

Karyotypes of males of house mice were studied in European and Asiatic areas of USSR. They are differentiated according to Y-chromosome morphology, two variants of which are discussed with respect to species-diagnostic differences. A «large» variant regards the 19th pair of autosomes, most common in indoor as well as outdoor samples, including biochemically tested Mus musculus and M. m. domesticus. A substantially «small» variant was found , in wild short-tailed mice only. The miniature Y-chromosome was also detected during analysis of karyograms of M. spretus from the western Mediterranean. The three taxa with unique miniature Ychromosome seem to correspond to three subspecies, which were considered to be united in a separate species, Mus spicikgus. The possibility of using the new simple cytogenetic marker for diagnosis of. sympatric mice populations of two presumably distinct species, M. musculus and M. spialegus, and for historic reconstructions of their man-related distribution is discussed.

Here we report on the analysis of three rodent sibling species complexes belonging to the African genera Arvicanthis, Acomys and Mastomys. Using cytogenetic and molecular approaches we set out to investigate how karyotype and molecular evolution are linked in these muroid sibling species and, in particular, to what extent chromosomal changes are relevant to cladogenic events inferred from molecular data. The study revealed that each complex is characterized by a distinct pattern of karyotype evolution (karyotypic orthoselection), and a specific mutation rate. However we found that the general pattern may be considerably modified in the course of evolution within the same species complex (Arvicanthis, Acomys). This observation suggests that karyotypic orthoselection documented in numerous groups is not so much a reflection of selection of a definite type of chromosomal mutation, as suggested by the classical concept, but is due to genome structure of a given species. In particular, karyotypic change appears related to the quantity and chromosomal location of repeated sequences. The congruence between the chromosomal and molecular data shows that chromosomal changes are often valuable phylogenetic characters (Arvicanthis and Mastomys, but not Acomys). However, most importantly the approach underscores the value of incorporating both in order to gain a better understanding of complex patterns of evolution. Moreover, the fact that every cladogenetic event in Mastomys is supported by two pericentric inversions allowed us to hypothesize that genetic differentiation is initiated by the suppression of recombination within inverted segments, and that the accumulation of multiple pericentric inversions reinforces genetic isolation leading to subsequent speciation. Finally, the low sequence divergences distinguishing karyotypically distinct sibling species within Arvicanthis and Mastomys emphasizes the power of combining cytogenetic and molecular approaches for the characterization of unrecognized components of biodiversity.
