| Abstract: | Summary
Chelidonium majus shows a closed ring of 12 chromosomes at meiosis. The maintenance of this translocation heterozygosity is assured by a balanced combination of lethal alleles. The fertility is estimated to be 60–70%. In spite of its genetic system and its wide distribution, the genus is monospecific. |
