title: [Variability of satellite DNA II and IV in cattle, various representatives of the subfamily Bovinae and their hybrids].
abstract: 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 breeds. The specific features of satellite IV organization in the bison, banteng and yak are revealed, allowing the use of the satellite as a specific genetic marker. Superposition of parental organizational types of this class of repeats is detected for the interspecies hybrids yak x cattle, banteng x cattle, and bison x cattle. At the same time, several cases of deviation from classic inheritance of such parental types in the interspecies hybrids were found.
