Heterothailism in Biflagellate Aquatic Fungi: Preliminary Genetic Analysis

J. Thomas Mullins 1 and John R. Raper 1

1 Biological Laboratories, Harvard University, Cambridge, Massachusetts

Genetic analysis of several hundred progeny from crosses of two heterothallic species of Achlya and Dictyuchus provides preliminary information about the life cycle and pattern of sexuality in the biflagellate Phycomycetes. Extensive testing of mycelial progeny indicates a diploid life cycle. Control of sexual expression and mating competence appears to be based on a complex genetic system.
