Karyotype variability of the ukrainian mountain-carpathian sheep breed
Keywords:
karyotype, chromosomal instability, sheep breedingAbstract
The main purpose of this work was to describe the karyotype variability of the Ukrainian Mountain-Carpathian sheep breed. Cytogenetic studies were carried out on a group of 25 sheep Ukrainian
Mountain-Carpathian breed. The cultivation of lymphocytes, preparing the cytogenetic samples, classification and registration of chromosome aberrations were held using conventional methods. It was
established that the number and structure of the chromosomes of sheep of the Ukrainian MountainCarpathian breed corresponds to the norm typical for this species of animals. Chromosomal variability of the studied population includes 19.22% of numerical and structural aberrations. By the number
and structure of the chromosome set of the Ukrainian Mountain-Carpathian sheep breed do not differ
from other breeds of sheep. Accurate identification of individual chromosomes with routine coloring
allows using cytogenetic studies in breeding practice in sheep breeding.
