Description of the Anser cygnoides goose karyotype.

The karyotype of the domestic goose A. cygnoides was characterised on the basis of R and C bands. Chromosomal preparations obtained from an in vitro culture of blood lymphocytes were stained by means of the RBG and CBG banding techniques. The first nine pairs of chromosomes were analysed by the R banding technique, while fourteen pairs of chromosomes were analysed by the C banding technique. The localisation of R bands as well as the sizes and positions of constitutive heterochromatin blocks were determined. Ideograms of R and C banded patterns for the analysed chromosomes were drawn. The morphological make-up of the analysed chromosomes was assessed.
