Recombination map of the common shrew, Sorex araneus (Eulipotyphla, Mammalia).
The Eurasian common shrew (Sorex araneus L.) is characterized by spectacular chromosomal variation, both autosomal variation of the Robertsonian type and an XX/XY(1)Y(2) system of sex determination. It is an important mammalian model of chromosomal and genome evolution as it is one of the few species with a complete genome sequence. Here we generate a high-precision cytological recombination ma...
متن کاملChromosome Synapsis and Recombination in Male Hybrids between Two Chromosome Races of the Common Shrew (Sorex araneus L., Soricidae, Eulipotyphla)
Hybrid zones between chromosome races of the common shrew (Sorex araneus) provide exceptional models to study the potential role of chromosome rearrangements in the initial steps of speciation. The Novosibirsk and Tomsk races differ by a series of Robertsonian fusions with monobrachial homology. They form a narrow hybrid zone and generate hybrids with both simple (chain of three chromosomes) an...
متن کاملKaryotypic differentiation of populations of the common shrew Sorex araneus L. (Mammalia) in Belarus
The common shrews, Sorex araneus Linnaeus, 1758, inhabiting the territory of Belarus, are characterized by a significant variation in the frequency of Robertsonian (Rb) translocations. The frequency clines for translocations specific of three chromosome races: the West Dvina (gm, hk, ip, no, qr), Kiev (g/m, hi, k/o, n, p, q, r), and Białowieża (g/r, hn, ik, m/p, o, q) have already been studied ...
متن کاملSex chromosome meiotic drive in hybrid males of the common shrew (Sorex araneus).
Patterns of sex chromosome segregation in six homozygous males of the common shrew (Sorex araneus LINNAEUS, 1758) belonging to two chromosomal races, as well as in 16 interracial hybrids were studied. Based on their karyotypes the hybrids can be subdivided into two groups: (a) complex heterozygotes, which form meiotic quadrivalents in chain and chain + ring configurations, and (b) complex heter...
متن کاملSeasonality of leptin levels in the BAT of the common shrew (Sorex araneus).
Leptin concentrations in the interscapular brown adipose tissue (IBAT) of the common shrew (Sorex araneus) were measured in different seasons. The leptin concentrations in IBAT were much higher than in the liver, where leptin is supposed to be of blood origin. In the heart muscle no detectable amount of leptin was found. There were clear seasonal variations in the leptin concentrations in IBAT....
