title: Cytogenetic variation in farmed stock of Dybowski's sika deer.
abstract: The chromosome constitution of Dybowski's sika deer was studied on the basis of 15 samples obtained from farmed stock maintained in an enclosure. The diploid chromosome number was 2n=68, 2n=67 and 2n=66. The constitutive heterochromatin (C-bands) was located in the centromeric regions of all acrocentric chromosomes. Metacentric chromosomes were C-negative. Chromosomes of three pairs proved to be NORs carriers. The size polymorphism of silver deposits was identified in two animals. A cytogenetic analysis indicated that the farmed stock of Dybowski's sika deer demonstrates considerable variation. The chromosome polymorphism observed may be a valuable marker for the management and preservation of this species.
