I propose the name “diagynic heredity” for this kind of heredity, as the sex-linked character is transmitted from male...

This report will review subsequent developments in this research, with special emphasis on the application of recombination analysis in bacteria to problems of general genetic interest. The standard textbooks of bacteri...
