In dojo loach (<i>Misgurnus anguillicaudatus</i>), although most wild types are gonochoristic diploids that genetically differentiated into 2 groups, A and B, clonal lineages appear in certain localities. Clonal loaches have been considered to hybrid origins between the groups by a series of genetic studies. this study, using FISH with newly developed probe (ManDra-A), we identified...

Elucidation of the genetic mechanisms convergent evolution, evolution similar or same phenotypes in phylogenetically independent lineages, helps predict how populations will respond to selective pressures. Convergent can be caused by either fixation identical-by-descent alleles, mutations at gene, different genes controlling trait. To what extent does alleles lead isolated where inflow adaptive...

Populations of threespine stickleback (Gasterosteus aculeatus) differ widely in spine number, extent of body armour, body depth, jaw length as well as many other traits [1] and provide an opportunity to gain insight into mechanisms of morphological diversification. The phenotypic differences are heritable but the gene(s) involved have not yet been identified [2]. We focused on the pelvic girdle...

Abstract In any U -abundant semigroup with an Ehresmann transversal, two significant components R and L are introduced in this paper described by Green’s ∼ \sim -relations. Some interesting properties associated explored some equivalent conditions for the transversal to be a quasi-ideal acquired. Finally, spined produc...

The structure of optical radiation emitted by the samples of loach fish eggs is studied. It was found earlier that such radiation perform the communications between distant samples, which result in the synchronization of their development. The photon radiation in form of short quasi-periodic bursts was observed for fish and frog eggs, hence the communication mechanism can be similar to the exch...

Various low-potential viologen dyes enhance light-induced absorption changes in the nearinfrared region (t.A870) in chromatophore preparations from Rhodospirillum rubrum in the presence of dichlorophenol indophenol and a high concentration of ascorbate (DCPIP + asc). An increase in t.A870 was also observed in large reaction-center preparations from R. rubrum with viologens in the presence of as...

Schistura phamhringi, new stone loach, is described from Dutah Stream, tributary of the Yu River (Chindwin basin), near Larong Village, Chandel District, Manipur, India. It is distinguished from all its congeners by a unique combination of characters: 6-7 black saddles, each continued on both flanks forming broad diamond-shaped black bars with narrow ventral margin; bars superimposed on a grey ...

Somatic and oocyte 5S rRNAs from the liver and unfertilized eggs of the loach (Misgurnus fossilis have been sequenced and found to differ in six nucleotides. All the substitutions are confined to the 5'-half of the molecules; 4 of them are pyrimidine-pyrimidine substitutions, and 2 are purine-pyrimidine ones. Considerable differences, both in the position and the character of substitutions, hav...
