The progress in Micromorphology and Biochemistry of the last decades has led to a rather far reaching understanding of the function of the genes. Much is also known about their morphological organization within the cell, particularly their reduplication and segregation in connection with the process of cell division. The intensive light microscopic studies of the earlier cytological era on cell division and chromosomes, which laid the basis for this understanding are very comprehensively covered by WASSERMANN (1929) in his masterly contribution "Wachstum und Vermehrung der lebendigen Masse"...

This volume was originally intended to be an English translation of the book MetllOden in der medizinischen Cytogenetik, published in 1970.

As a result, there are now twelve chapters instead of eight, and two additional authors have been called upon, Dr. KRONE and Dr. SCHNEDL.
