[Differential staining of hamadryas baboon chromosomes with Romanovsky-Giemsa dye (G-discs)].
The pattern of G-discs in the chromosomes of baboon (Papio hamadryas) was studied after staining by means of ASG method. On the basis of these data all the 20 pairs of autosomes and sex chromosomes were identified. According to the distinctness of the discs all the chromosomes were classified into 3 groups: well differentiated, faintly differentiated and moderately differentiated. The most distinct pattern of discs was obtained in slightly spiralized chromosomes. Dimorphism of the disc pattern in homologous chromosomes was observed, which is, possibly, indicative of their different functional activity.
