[Quantitative characteristics of the nucleolus organizer region of the chromosomes in the domestic pig].
Absolute and relative dimensions of Ag+-NORs and secondary constrictions (SC) of pig chromosomes were determined. Interchromosomal and interindividual variability of these indices were marked. An attempt was undertaken to standardize the absolute sizes of Ag+-NORs and SC, degrees of chromosome condensation being taken into consideration. A high correlation between the dimensions of Ag+-NOR and of SC was noted.
