"That the ability of the nucleolar organizer to form nucleoli is under genetic control has also been demonstratedin hybrids of the plant genus Grepis. Each species of Crepis has its distinctive nucleolar organizer, but when brought into a common nucleus through hybridization, the organizers exhibit differential synthetic ability in the hybrid environment; only one of them will form a nucleolus, the other remaining inactive. When inactive, no nucleolus forms and the secondary constriction will… CONTINUE READING
