Abstract
B-Chromosomes ofAllium flavum, A. stamineum andA. carinatum were C-banded. InA. flavum different types of B's were found, one of them possessing a nucleolus organizer. In the B's ofA. flavum andA. stamineum the banding patterns resemble those found in the standard chromosomes. The B inA. carinatum is only terminally banded. InA. flavum chiasma localization in the B's appears to be dependent on C-band location, just as is the case in the A-chromosomes. An increase in B's was found to cause a small (but significant) increase in chiasma frequency in the PMC's. This may result from an alteration in the nucleotype by the B's.
