Cytogenetic characteristics of cattle at different methods of growing
Keywords:
chromosomes, aberrations, interspecific and breed crossing of animals, cytogenetic marker.
Abstract
The purpose. Determination of cytogenetic characteristics of animals at different stages of selection process. Methods. Cultivation of lymphocytes, preparation of cytogenetic specimens, grading and record-keeping of aberrations of chromosomes is realized using standard procedures. Results. It is fixed that in karyotypesof the animals got as a result of interspecific crossings,aberrations of chromosomes were twice more, than at crossing hybrids and purebreds. Conclusions. At building multicomponent breeds of animals cytogenetic features (individual and pedigree) can play the role of genetic marker.
