...Kohei Washio; Shusei Mizushima; Takamichi Jogahara; Asato Kuroiwa Two species of spiny rats, Tokudaia osimensis and Tokudaia tokunoshimensis , show an X0/X0 sex chromosome constitution due to the lack of a Y chromosome. The Sry gene has been completely lost from the genome of these species. We...

...Terje Raudsepp; Bhanu P. Chowdhary The pseudoautosomal region (PAR) is a unique segment of sequence homology between differentiated sex chromosomes where recombination occurs during meiosis. Molecular and functional properties of the PAR are distinctive from the autosomes and the remaining regions...

..., mainly in the sex chromosomes. The FISH physical mapping revealed that both Rex1 and Rex3 elements are dispersed in small clusters throughout the chromosomes of all cytotypes analyzed. However, conspicuous blocks occur in several samples, including an accentuated accumulation of the Rex3 element in X 1...

... and morphologically similar chromosomes. The sister group relationship between the Centrolenidae and Allophrynidae (unranked taxon Allocentroleniae) is clearly corroborated by the cytogenetic data. The existence of heteromorphic XY♂/XX♀ sex chromosomes in an initial stage of morphological differentiation...
