FURTHER RESEARCH ON THE CONTROL OF FISSIONING IN PLANARIANS
SUMMARY Variations occur in chromosome number through a gradual increase in originally diploid or polyploid sets, accompained by intra-individual oscillations. In many species or races the hyperdiploid or polyploid sets have B-chromosomes. In some species fissiparity is accompanied by such genomic deviations but so far there is no proof that the two events are necessarily correlated. Numerical variations and fissiparity could propagate due to some reciprocal advantage in certain natural habitats and in the laboratory.
