To describe genetic variability and population diversity in domesticated populations of American bison (Bison bison), aurochs (Bison bonasus), and gray Ukrainian cattle (Bos taurus) different variants of DNA fingerprinting technique (utilizing the M13 phage DNA, (TTAGGG)4 synthetic oligonucleotide, and three arbitrary primers as hybridization probes) were(More)
Genome fingerprinting with a hypervariable minisatellite sequence of phage M13 DNA was used to study the genetic variation in individual species of the genera Bosand Bison(subfamily Bovinae) and in their interspecific and intergeneric hybrids. DNA fingerprints were obtained for domestic cow Bos taurus primigenius, vatussy Bos taurus macroceros, banteng Bos(More)
Polymorphism of satellite DNA II and IV was studied in Bos taurus by means of Southern blotting and dot hybridization. Of primary interest is the absence of restriction fragment length polymorphism at the individual and interbreed levels. Differences in the content of satellite II in the genome are demonstrated for animals of the Kholmogorskaya and Yakutian(More)
Analysis of blood serum proteins electrophoretic spectra for perching and domestic ducks resulted in revealing interspecific differences of prealbumin and transferrin types showing incomplete identity of loci in analogous sites of some homologous chromosomes in the hybridizants. This confirms the genetic nature of sterility in this crossing combination(More)
Spermium morphology was studied in 7 species of Carnivora representatives. Their clear distinctions reflecting genetic relations between certain species of animals in the zoological series are established. Genetical determination of the spermium morphology is confirmed by the data of the hybridization analysis.
Data of analysis of morphogenetic character of spermii in 100 species of mammals and some hybrid forms, anatomical and physiological peculiarities of reproduction of animals of various taxonomic groups, reproduction and biological suitability of generative elements of distant hybrids reflect their biological interrelation in the zoological series. It is(More)
Hybridization of the domestic hen and the guinea fowl is accompanied by low fertility of eggs, high embryonic mortality of hybrid embryos and feti at various development stages and absolute sterility of the hybrid progeny. Cytological analysis of the hybrids obtained reveals heteromorphity of the 6th pair of their chromosomes although the character of the(More)
The hybrid progeny of F1 produced by crossing of banteng and domestic cow is characterized by absolute sterility of the male line and fertility of the female line. The crossbred males become fertile in further progenies while crossing cross-females with males of initial forms. Successful use of inter-subgenetic hybrids of banteng and domestic cow in(More)
Modifications of similar type were noted in the number of multiple AMY-1 forms of amylase isozyme for various species of Artiodactyla. It is supposed that these modifications are linked to periodical activation during evolution of genes responsible for modification of the molecules. Data obtained on Bovinae hybrids testify to this point of view.(More)
