Abstract

The karyotype of the Eiropean wild pig (Sus scrota scrofa L.) was analysed by means of silver-staining and the chromomycln A3/distamycln A/DAPI fluorescent bandng technique to locate active NORs and to differentiate types of C-bands. The ribosomal RNA genes are localized at the secondary constrictions of chromosomes 8 and 10. All biarmed chromosomes, with the exception of chromosome 15/17 and the Y, had a chromomycin bright centromeric region that was moderately fluorescent with dlstamycln A/DAPI (DA/DAPI). Conversely, all acrocentrlc chromosomes and the Robertsonian fusion product (15/17) exhibited DA/DAPI bright centromeric heterochromatin. The results are compared with the chromosomal staining behavior of the domestic pig (Sus scrofa domestlca L.) and discussed with respect to presumptive mechanisms of karyotyplc evolution.
