FURTHER STUDIES ON THE GENETICS OF

SUMMARY The purpose of the present work is to expand our state of knowledge of the genetic basis of incompatibility in a Honduran isolate of Didym- ium iridis. This is necessary in order to provide a foundation for the next step in the study of incompatibility. The nature of the incompati- bility reaction and the role of the individual loci can only be determined with well-defined genetic material. The diplohaplontic life cycle of Myxomycetes, in which both genera- tions can be maintained and manipulated genetically, is a great research asset but it can also be confusing because of these unique features.
